Starch metabolism is known to be an important pathway in the growth and development of plants. This study was conducted to investigate the genome-wide identification and structural analysis of genes encoding uridine diphosphate glucose pyrophosphorylase (UGPase), a key enzyme in starch synthesis in cassava, and to analyze the expression profiles of these genes based on publicly available RNA-seq data.

The aim of the thesis "Copreneurial sustainability: optimizing structures in small and medium U.S. enterprises" is to identify structures that support long-term sustainability of the copreneurial enterprise and its subsystems. To support the aim of the thesis, the following research question was derived from the literature review: What optimizing structures are created by copreneurs to achieve sustainability of both the business and the family?

Knema is a genus of tropical evergreen trees of the family Myristicaceae found in South East Asian countries such as Vietnam, Thailand, and Malaysia. In this paper, four lignans, (+)-pinoresinol (1),(+) epi-pinoresinol (2), piperitol (3), and pluviatilol (4), were isolated from the ethyl acetate extract of the fruit of Knema pachycarpa, an indigenus tree in Vietnam. The chemical structures were determined by spectroscopic data and comparison with the reported literature. These compounds were isolated from Knema genus for the first time.

2’,3’-Dideoxynucleosides (ddNs) are the most important class of compounds active against HIV/AIDS. They act as DNA chain terminators and competitive inhibitors of viral reverse transcriptase (RT). Currently, stavudine (d4T, Zerit) is one six drugs belonging to the ddNs family that are approved by the FDA. This article describes the synthesis of generic stavudine drug from thymidine in three steps. By mean of this synthesis, stavudine was obtained in a good yield. The structure of product and intermediate were established by NMR spectroscopies.

Angelica sinensis (OLiv.) Diels ("Danggui") belongs to the family Umbelliferae. Its rhizomes are reputed to have marked restorative, antianaemic and haemagogic properties. From ethyl acetate and butanol extracts of rhizomes of this plant 8 nitrogen-containing compounds (1-8) have been isolated. Their structures were elucidated by means of MS and NMR spectroscopic methods as 5-oxo-proline, 5-oxo-prolin-ethylester, nicotinamide, tryptophane, perlolidine, 1,2,3,4-tetrahydro-1-methyl- -carboline-3-carboxylic acide, adenosine and uridine.

The development of concept in structural morphology lets description the location of nickel nanoclusters in conductive organic polymers, which may be a new kind of structure in conductive organic polymer composites family. As a new route, such the development was supported by electrochemical two-pot process, on which polianiline containing nanoclusters of nickel incorporated in layer by layer were prepared, in H2SO4 0.1 M solutions. The presence of nickel nanoclusters in polymer matrix and the changes in morphology were confirmed by SEM/EDS

Mer belongs to the Tyro 3 family of receptor tyrosine kinases (RTKs). Together with Axl and Rse, the three RTKs are believed to play important functional roles in the male gonads because gene knockout male mice lacking all of these receptors are infertile. In the present study, postnatal expression of Axl and Rse in mouse testes decreased during maturation while expression of Mer increased age-dependently during testicular development.

In this study we describe the isolation of three genes of the CYP11B family of the guinea pig. CYP11B1 codes for the previously described 11b-hydroxylase [Bulow, H.E., Mobius, ¨ ¨ K., Bahr, V. & Bernhardt, R. (1996) Biochem. Biophys. Res. ¨ Commun. 221, 304–312] while CYP11B2 represents the aldosterone synthase gene. As no expression for CYP11B3 was detected this gene might represent a pseudogene.

The design of b-glycosidases with planed substrate specificity for biotechnological application has received little attention. This is mostly a consequence of the lack of data on the molecular basis of the b-glycosidase specificity, namely data on the energy of the noncovalent interactions in the enzymetransition state complex. In an attempt to fill this gap, sitedirected mutagenesis and enzyme steady-state kinetic experiments with different substrates were conducted, using as model a digestive b-glycosidase (glycoside hydrolase family 1) from Spodoptera frugiperda (Lepidoptera) (Sfbgly50).

In the biosynthesis of the antiarrhythmic alkaloid ajmaline, polyneuridine aldehyde esterase (PNAE) catalyses a central reaction by transforming polyneuridine aldehyde into epivellosimine, which is the immediate precursor for the synthesis of the ajmalane skeleton. The PNAE cDNA was previously heterologously expressed in E. coli. Sequence alignments indicated that PNAE has a 43% identity to a hydroxynitrile lyase from Hevea brasiliensis, which is a member of the a/b hydrolase superfamily. The catalytic triad, which is typical for this family, is conserved.
