Environmental conservation

This article provides an overview of methods for creating eco-friendly products using two primary materials: recycled coffee grounds and plastic bottles within the textile industry. Integrating technology and utilizing recycled materials significantly contribute to producing valuable products that aid in environmental conservation and promote sustainable manufacturing.

This thesis explores the problem of wasteful fashion consumption in light of the current need for individuals to develop a sustainable way of living. The Agenda 21 report from the Rio Earth Summit (1992) determined that sustainable consumption is an issue to be addressed in terms of resource conservation, waste reduction and a reduction of production pollutants. To date, in Australia, there are no policies or strategies in place to reduce wasteful consumption from the consumer’s perspective and it is this research and policy deficit that this thesis research addresses.

Ravine ecosystems are highly dynamic and completely deformatted terrain landscape. In these regions, Indigenous plant species are playing significant role in environmental rehabilitation because of their exultant survival and high adaptation to local conditions. Despite this, very little information’s available about existence of medicinal plants on the typical ravine flora. The present study attempted to explore the diversity and distribution of medicinal plant flora in the Yamuna ravines of Agra (U.P) and Chambal ravines of Kota district (Rajasthan).

The development of fruits without fertilization is known as parthenocarpy. Parthenocarpy improves the fruit quality, processing attributes, production and productivity of vegetable crops like tomato, cucumber, watermelon etc. Absence of seeds can enhances the shelf life of the fruits, allowing a better conservation, fruit set in adverse climatic conditions, early and offseason production of vegetable crops. Therefore, it is important to ensure yield stability regardless of environmental conditions.

Mikrobiologisches Institut der Eidgeno¨ssischen Technischen Hochschule, ETH-Zentrum, Zu¨rich, Switzerland The membrane-bound b subunit of the oxaloacetate decarboxylase Na+ pump of Klebsiella pneumoniae catalyzes the decarboxylation of enzyme-bound biotin. This event is coupled to the transport of 2 Na+ ions into the periplasm and consumes a periplasmically derived proton. The connecting fragment IIIa and transmembrane helices IV and VIII of the b subunit are highly conserved, harboring residues D203, Y229, N373, G377, S382, and R389 that play a profound role in catalysis. ...

Protein phosphatase 2A (PP2A) is an abundant heterotri-meric serine/threonine phosphatase containing highly con-served structural (A) and catalytic (C) subunits. Its diverse functions in the cell are determined by its association with a highly variable regulatory and targeting B subunit. At least three distinct gene families encoding B subunits are known: B/B55/CDC55, B¢/B56/RTS1 and B¢¢/PR72/130. No homologyhasbeen identi®edamong theBfamilies, and little is knownabout howtheseBsubunits interactwith the PP2A A and C subunits....

The merozoite surface protein-1 represents a prime candi-date for development of a malaria vaccine. Merozoite sur-face protein-1 has been shown to demonstrate high-activity peptide binding to human red blood cells. One of the high-activity binding peptides, named 5501, located in the N-terminus (amino acid sequence MLNISQHQCVKKQ CPQNS) of the 19-kDa molecular mass fragment of mero-zoite surface protein-1, is conserved, nonimmunogenic and nonprotective.

We introduce the basic concepts and develop a theory for nonequilibrium steady-state biochemical systems applicable to analyzing large-scale complex isothermal reaction networks. In terms of the stoichiometric matrix, we dem-onstrate both Kirchhoff’s flux lawR‘J‘ ¼0 over a bio-chemical species, and potential law R‘l‘ ¼0overa reaction loop. They reflect mass and energy conservation, respectively.

Cold shock proteins (CSPs) form a family of highly conserved bacterial proteins capable of single-stranded nucleic acid binding. They are suggested to act as RNA chaperones during cold shock inhibiting the formation of RNA secondary structures, which are unfavourable for transcription and translation.

Class III adenylyl cyclases usually possess six highly conserved catalytic residues. Deviations in these canonical amino acids are observed in several putative adenylyl cyclase genes as apparent in several bacterial genomes. This suggests that a variety of catalytic mechanisms may actually exist. The geneRv0386from Mycobacterium tuberculosiscodes for an adenylyl cyclase catalytic domain fused to an AAA-ATPase and a helix-turn-helix DNA-binding domain.

The AAA-peroxins Pex1p and Pex6p play a critical role in peroxisome bio-genesis but their precise function remains to be established. These two peroxins consist of three distinct regions (N, D1, D2), two of which (D1, D2) contain a conserved
230 amino acid cassette, which is common to all ATPases associated with various cellular activities (AAA). Here we show that Pex1p and Pex6p from Saccharomyces cerevisiaedo interact in vivo. We assigned their corresponding binding sites and elucidated the importance of ATP-binding and -hydrolysis of Pex1p and Pex6p for their interaction. ...

Two chloroplast phosphoglycerate kinase isoforms fromthe photosynthetic flagellateEuglena graciliswere purified to homogeneity, partially sequenced, and subsequently cDNAs encoding phosphoglycerate kinase isoenzymes from both the chloroplast and cytosol of E. graciliswere cloned and sequenced. Chloroplast phosphoglycerate kinase, a mono-meric enzyme, was encoded as a polyprotein precursor of at least four mature subunits that were separated by conserved tetrapeptides.

A homologue of interleukin 18 has been identified from rainbow trout,Oncorhynchus mykiss. The trout IL-18gene spans 3.7 kb and consists of six exons and five introns, sharing the same gene organization with its human coun-terpart. The putative translated protein is 199 amino acids in length with no predicted signal peptide. Analysis of the multiple sequence alignment reveals a conserved ICE cut site, resulting in a mature peptide of 162 amino acids. The trout IL-18 shares 41–45% similarity with known IL-18 molecules and contains an IL-1 family signature motif....

NA helicases are ubiquitous molecular motor proteins which harness the chemical free energy of ATPhydrolysis to catalyze the unwinding of energetically stable duplex DNA, and thus play important roles in nearly all aspects of nucleic acid metabolism, including replication, repair, recombina-tion, and transcription. They break the hydrogen bonds between the duplex helix and move unidirectionally along the bound strand. All helicases are also translocases and DNA-dependentATPases.Most contain conserved helicase motifs that act as an engine to power DNA unwinding. ...

TheB class cell-attachedephrinsmediate contact-dependent cell–cell communications and transduce the contact signals to the host cells through the binding interactions of their cytoplasmic domains. Two classes of intracellular effectors of B ephrins have been identified: one contains the PSD-95/ Dlg/ZO-1 (PDZ)domain(for examplePDZ-RGS3), and the second the Src homology 2 (SH2) domain (e.g. the Grb4 adaptor protein).

Cyclotides are a family of bioactive plant peptides that are characterized by a circular protein backbone and three conserved tightly packed disulfide bonds. The antimicrobial and hemolytic properties of cyclotides, along with the relative hydrophobicity of the peptides, point to the biological mem-brane as a target for cyclotides.

The molecular mechanisms of the DNA mismatch repair (MMR) system have been uncovered over the last decade, especially in prokaryotes. The results obtained for prokaryotic MMR proteins have provided a frame-work for the study of the MMR system in eukaryotic organisms, such as yeast, mouse and human, because the functions of MMR proteins have been conserved during evolution from bacteria to humans.

The protein ataxin-3 is responsible for spinocerebellar ataxia type 3, a neu-rodegenerative disease triggered when the length of a stretch of consecutive glutamines exceeds a critical threshold. Different physiologic roles have been suggested for this protein. More specifically, recent papers have shown that the highly conserved N-terminal Josephin domain of ataxin-3 binds ubiquitin and has ubiquitin hydrolase activity, thanks to a catalytic device specific to cysteine proteases.
