The C2H2 zinc finger protein ZAT12 has been classified as a plant core abiotic stress response gene in the early response to multiple stresses. ZAT12 links the iron deficiency and oxidative stress responses through the direct interaction with/and negative regulation of a central regulator - FIT.

Studies on nanoparticle-protein interaction have also not been studied. This would give information on ratio influence on the structural alteration of EGCg in EGCg-AuNPs and its functionality in vivo. Herein, the optimisation of EGCg-AuNPs will be determined with a large pool of stoichiometric synthesises of gold and EGCg. These optimised EGCg-AuNPs would then be studied with bovine serum albumin (BSA) for protein interactions, binding and thermodynamics.

The thesis is structured as follows: In Chapter 1, the scientific literature is summarized within the scope of this study. Chapter 2 provides a comprehensive overview of the principles of the applied computational approaches in this study. Chapter 3 identifies the important residues of the LsIA/α7 nAChR complex that affect the interactions between the toxin and the membrane protein due to C-terminal carboxylation of LsIA. The effects of C-terminal modification of LsIA on interactions with α3β2 nAChR, involved in cardiovascular diseases, were also investigated in Chapter 4.

RNA polymerase II (Pol II) is a 12 subunit protein complex from yeast to human that is required for gene expression. Gdown1 containing Pol II [Pol II (G)] is a special form of Pol II that is catalytically inactive and heavily depends on the 30-subunit Mediator complex for its activator and basal dependent function in vitro. Here we report for the first time, the identification and the generation of a 15-subunit human Mediator complex via the novel multibac baculovirus expression system that is fully responsive to Pol II (G).

Polyhydroxyalkanoate (PHA) is stored as an important carbon and energy source in bacterial cells. For biomedical applications, gram-positive bacteria can be better sources of PHAs, since they lack outer membrane lipopolysaccharide. Although gram-positive Streptomyces coelicolor A3(2) has been indicated as a high potential PHA producer, phaC gene that encodes the key enzyme PHA synthase in the metabolic pathway is not determined in its genome.

G-quadurplex (G4) formation plays a role in many biological processes such as replication, transcription, translation, and telomeric maintenance. Stabilization of G4 structure by peptide has recently emerged as a potential approach in the regulation of protein expression. In this study, we reported on regulation of cyan fluorescent protein (CFP) expression by the interaction of G4 and RNA helicase associated with AU-rich elements (RHAU) peptide in E. coli.

In this paper, we present a novel global protein-protein interaction network alignment algorithm, which is enhanced with an extended large neighborhood search heuristics. Evaluated on benchmark datasets of yeast, fly, human and worm, the proposed algorithm outperforms state-of-the-art algorithms. Furthermore, the complexity of ours is polynomial, thus being scalable to large biological networks in practice.

Chapter 11 - general transcription factors in eukaryotes. Eukaryotic RNA polymerases, unlike their bacterial counterparts, are incapable of binding by themselves to their respective promoters. Instead, they rely on proteins called transcription factors to show them the way. Such factors are grouped into two classes: general transcription factors and gene-specifi c transcription factors (activators). In this chapter we will survey the general transcription factors that interact with all three RNA polymerases and their promoters.

In the present article, we address the question that how important role do the Quantum Mechanic (QM) and Molecular Mechanics (MM) forces play in ligand docking on protein, via the use semi-quantum relaxation approach (SQRA) using different forces, e.g. quantum, Van der Waals and Coulomb ones, in the process of ligand - protein docking. The QM approximation is applied to calculate the QM forces of neighbor protein-atoms acting on ligands. The L-J 6-12 empirical potential model and Coulomb rule are applied to calculate the forces from the rest protein-atoms on each ligand - atom.

In the course of trying to understand the pathogenesis of leishmaniasis in relation to extracellular matrix (ECM) elements, laminin, a major ECM protein, has been found to bind saturably and with high affinity to a 67-kDa cell surface protein of Leishmania donovani. This interaction involves a single class of binding sites, which are ionic in nature, conformation-dependent and possibly involves sulfhydryls. Binding activity was significantly enhanced by Zn2+, an effect possibly mediated through Cys-rich zinc finger-like sequences on laminin....

Trehalose metabolism is an essential component of the stress response in yeast cells. In this work we show that the products of the principal genes involved in trehalose metabolism in Schizosaccharomyces pombe, tps1+ (coding for trehalose6-P synthase, Tps1p), ntp1+ (encoding neutral trehalase, Ntp1p) and tpp1+ (that codes for trehalose-6-P phosphatase, Tpp1p), interact in vitro with each other and with themselves to form protein complexes. Disruption of the gene tps1+ blocks the activation of the neutral trehalase induced by heat shock but not by osmotic stress.

This study addresses the interactions between the adaptor protein Shb and components involved in T cell signalling, including SLP-76, Gads, Vav and ZAP70. We show that both SLP-76 and ZAP70 co-immunoprecipitate with Shb in Jurkat T cells and that Shb and Vav co-immunoprecipitate when cotransfected in COS cells. We also demonstrate, utilizing fusion protein constructs, that SLP-76, Gads and Vav associate independently of each other to different domains or regions, of Shb.

The insect ecdysteroid receptor consists of a heterodimer between EcR and the RXR-orthologue, USP. We addressed the question of whether this heterodimer, like all other RXR heterodimers, may be formed in the absence of ligand and whether ligand promotes dimerization. We found that C-terminal protein fragments that comprised the ligand binding, but not the DNA binding domain of EcR and USP and which were equipped with the activation or DNA binding region of GAL4, respectively, exhibit a weak ability to interact spontaneously with each other.
