Background: The present study has been designed with the aim of evaluating A-kinase anchoring proteins 3 (AKAP3)and Procollagen-Lysine, 2-Oxoglutarate 5-Dioxygenase 3 (PLOD3) gene mutations and prediction of 3D proteinstructure for ligand binding activity in the cases of non-obstructive azoospermic male.Materials and Methods: Clinically diagnosed cases of non-obstructive azoos...

background: the mesobuthus eupeus scorpion venoms are known to contain α-toxin peptides, many of which interfere with k+ ion channel function. these toxin peptides have important value in  the pharmacology and physiology studies of specific k+ channel of cells. objectives: given the  lack of information of the molecular biology of peptides in the toxin of iranian scorpions, the aim of this stud...

background: many plant growth-promoting bacteria including rhizobia contain the 1-aminocyclopropane-1-carboxylate (acc) deaminase enzyme that can leave acc, and thereby lower the level of ethylene in stressed plants. drought and salinity are the most common environmental stress factors for plants in iran. objectives: the main aim of this research was development of bio-fertilizers containing ac...

background: stearoyl-coa desaturase (scd) is a key enzyme that converts saturated fatty acids (sfas) to monounsaturated fatty acids (mufas) in fat biosynthesis. despite being crucial for interpreting scds’ roles across species, the evolutionary relationship of scd proteins across species has yet to be elucidated. this study aims to present this evolutionary relationship based on amino acid sequ...
