Background: Septins are members of highly conserved polymerizing GTP binding proteins well described in the animal kingdom. 14 Septin proteins have been characterized in humans (SEPT1-SEPT14), some of which are tissue-specific. All of 14 genome-mapped human septins contain a highly conserved central GTP-binding domain which is very critical in GTPase signaling properties as well as oligomerizat...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
abstract: the present thesis includes ; one preface and 11speeches , that each speech considered in different researches . the prefact part , studied grammer back ground , the first speech considered a brief description about grammatical credits . the second speech considered the different typs of sentences , from structure and meaning points of view . the third speech considered the verb es...
EfeB/YcdB is a member of the dye-decolorizing peroxidase (DyP) protein family. Recent study has shown that this protein can extract iron from heme without breaking the tetrapyrrole ring. We report the crystal structure of EfeB from E. coli O157 bound to heme at 1.95 Å resolution. The EfeB monomer contains two domains. The heme molecule is located in a large hydrophobic pocket in the C-terminal ...
SIRT6 is a member of the evolutionarily conserved sirtuin family of NAD(+)-dependent protein deacetylases and functions in genomic stability and transcriptional control of glucose metabolism. Early reports suggested that SIRT6 performs ADP-ribosylation, whereas more recent studies have suggested that SIRT6 functions mainly as a histone deacetylase. Thus, the molecular functions of SIRT6 remain ...
Arrestins (arr) are multifunctional cytosolic adaptors that bind to active and phosphorylated G protein-coupled receptors (GPCRs) via a highly versatile interface. stop protein signaling trigger other pathways. Recently, 3D structures of arr–GPCR complexes have been solved, which provide bulk structural information for understanding the mechanism arr recruitment activation. However, many questi...
