Identification and characterization of sporulation gene spoVS from Bacillus subtilis.
We report the identification and characterization of an additional sporulation gene from Bacillus subtilis called spoVS, which is induced early in sporulation under the control of sigma H. We show that spoVS is an 86-codon-long open reading frame and is capable of encoding a protein of 8,796 Da which exhibits little similarity to other proteins in the databases. Null mutations in spoVS have two...
متن کاملMOLECULAR CLONING AND EVALUATION OF WILD PROMOTER IN EXPRESSION OF BACILLUS SPHAERICUS PHENYLALANINE DEHYDROGENASE GENE IN BACILLUS SUBTILIS CELLS
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...
متن کاملPurification and Characterization of Thermostable Pullulanase from Bacillus stearothermophilus and Molecular Cloning and Expression of the Gene in Bacillus subtilis.
A thermostable pullulanase (alpha-dextrin 6-glucanohydrolase [EC 3.2.1.41]) from a newly isolated Bacillus stearothermophilus strain (TRS128) was purified and characterized. The enzyme hydrolyzed (1-->6)-alpha-d-glucosidic linkages of pullulan to produce maltotriose, and the optimum temperature was 65 degrees C. About 90% of the enzyme activity was retained after treatment at 65 degrees C for 6...
متن کاملMolecular Diagnosis and Characterization of Bacillus subtilis Isolated from Burn Wound in Iran
Background: Bacillus subtilis refers to stretched and sometimes curved, gram-positive, aerobic, and catalase-positive bacilli, which has thermo-resistant endospores. It has been known as a normal flora in the human but can be pathogens In the case of opportunistic. Also, it can be the pathogen of nosocomial infections such as wound among hospitalized patients. Purpose of this study was to ident...
متن کاملCloning and Enhanced Expression of an Extracellular Alkaline Protease from a Soil Isolate of Bacillus clausii in Bacillus subtilis
in the detergent industry. In this study, the extracellular alkaline serine protease gene, aprE, from Bacillusclausii was amplified by PCR and further cloned and expressed in B. subtilis WB600 using the pWB980 expression vector. Protease activity of the recombinant B. subtilis WB600 harboring the plasmid pWB980/aprEreached up to 1020 U/ml, approximately 3-folds higher than the nativ...
