Background: Staphylococcus aureus (S. aureus), an important pathogen, causes a wide range of infections in human starting from food poisoning to septicemia. It affects the host cells with various exotoxins, known as virulence factors, which are synthesized in growth phase-dependent manner of the bacteria. S. aureus has been reported to become resistant to antibiotics rapidly. Among two common clinical isolates, Methicillin-s Read More

Background: The Cytochromes P450 (CYPs) have an essential role in the oxidation of endogenous and exogenous molecules. The CYPs are identified in all domains of life, but the CYP152A1 from Bacillus subtilis is specially considered for clinical and industrial applications. The molecular cloning of a new type of CYP from Bacillus subtilis was reported, previously. Here, we describe the hidden layer of biological information Read More

Background: Cervical cancer arises from the cervix and it is the 3rd most diagnosed malignancy and a foremost cause of cancer-related death in females. On the other hand, the expressions of EGFR and p53 are two important proteins observed in various studies on cervical cancer. Objective: The study aims to evaluate the beneficial effect of radiotherapy based on the regulation of p53 and EGFR gene in patients with cervical Read More

Background: The firefly luciferase enzyme is widely used in protein engineering and diverse areas of biotechnology, but the main problem with this enzyme is low-temperature stability. Previous reports indicated that surface areas of thermostable proteins are rich in arginine, which increased their thermal stability. In this study, this aspect of thermophilic proteins evaluated by mutations of surface residues to Arg. Here, we rep Read More

Background: The 1,4-alpha-glucan branching protein (GlgB) plays an important role in the glycogen biosynthesis and the deficiency in this enzyme has resulted in Glycogen storage disease and accumulation of an amylopectin-like polysaccharide. Consequently, this enzyme was considered a special topic in clinical and biotechnological research. One of the newly introduced GlgB belongs to the Neisseria sp. HMSC071A01 (Ref.S Read More

Background: Oral Squamous Cell Carcinoma (OSCC) is a major sub-type of oral cancer that shares 90% proportion of oral cavity cancers. It is declared as the sixth most frequent cancer among all cancer types throughout the world. Higher morbidity in Asian countries is reported due to frequent use of Smokeless Tobacco (SLT) products besides exposure to other risk factors. Hyperactivation of epidermal growth factor re Read More

Background: Hyperuricemia and gout are the conditions, which is a response of accumulation of uric acid in the blood and urine. Uric acid is the product of purine metabolic pathway in humans. Uricase is a therapeutic enzyme that can enzymatically reduces the concentration of uric acid in serum and urine into more a soluble allantoin. Uricases are widely available in several sources like bacteria, fungi, yeast, plants and ani Read More

Background: Familial Mediterranean Fever (FMF) is a prototypical hereditary autoinflammatory disease affecting principally Mediterranean populations and characterized by recurrent frequent fever and inflammation. The disease is essentially caused by inherited mutations in the MEFV gene which encodes pyrin protein. The reported mutations are mostly located on the B30.2 domain in the C-terminal end of the protein. Read More
