Background and Objective: Secretory extracellular Phospholipases are generally involved in hydrolysis of extracellular phospholipids and thus providing nutritive source of carbon, nitrogen, and phosphate. However, intracellular phospholipases perform metabolic functions and adjust biologic activities. Synthesis of phospholipases in different pathogenic microorganisms and their mode of action in...
objective: despite using the bacille calmette guerin (bcg) vaccine, tuberculosis (tb) is still a worldwide disease that kills 2-3 million people each year. developing a new and more effective vaccine is one way to possibly reduce the morbidity and mortality of tb. the mtb72f vaccine is one of the important subunit vaccines applied in human clinical trials. in this study, we have constructed an ...
Introduction & Objective: Bone morphogenetic proteins are a group of cytokines that belongs to superfamily TGFβ. These proteins play an important role in evolution of many of organs and tissues through germinal period followed by amending and rebuilding of bone tissue and car-tilage. The aim of this study was to clone and expression analysis of BMP-2 gene in E. coli bacteria. Materials & Method...
Background and purpose: Staphylococcus aureus is an important nosocomial pathogen which causes some diseases such as endocarditis, osteomyelitis, pneumonia, toxic shock syndrome, and food poisoning. The excessive and inappropriate use of antibiotics in the treatment of these diseases causes resistance to many antibiotics. Lysostaphin is an effective agent in the treatment of staphylococcal infe...
the use of organophosphorus hydrolase (oph) enzyme to degrade chemical warfare agents is one of the most frequently used decontamination methods. oph is a ~36 kda homodimeric metalloprotein that is found in the membrane of flavobacterium sp. strain atcc 27551 and brevundimonas diminuta mg and is capable of hydrolyzing a wide range of oxon and thion , such as paraoxon and parathion. oph gene ( o...
To evaluate the role of wild promoter of L-phenylalanine dehydrogenase (PheDH) gene, referred to as pdh, from Bacillus sphaericus in expression, cloning of pdh gene in Bacillus subtilis was performed. The whole pdh gene was cloned in pHY300PLK shuttle vector and amplified, construct (pHYDH) then transformed in B. subtilis ISW1214 and E. coli JM109. The pdh endogenous promoter presented no effec...
