Cloning 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...
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 کاملCloning and characterization of the groESL operon from Bacillus subtilis.
The sequence of the 10 N-terminal amino acids of a Bacillus subtilis protein that cross-reacts with antibody to Escherichia coli GroEL was used to design a set of degenerate oligonucleotide probes. These probes identified a clone which carries almost the entire groESL operon from a B. subtilis subgenomic library. By chromosomal walking, an additional fragment carrying the 3' end of groESL and i...
متن کاملCloning and Expression of Thermostable alpha-Amylase Gene from Bacillus stearothermophilus in Bacillus stearothermophilus and Bacillus subtilis.
The structural gene for a thermostable alpha-amylase from Bacillus stearothermophilus was cloned in plasmids pTB90 and pTB53. It was expressed in both B. stearothermophilus and Bacillus subtilis. B. stearothermophilus carrying the recombinant plasmid produced about fivefold more alpha-amylase (20.9 U/mg of dry cells) than did the wild-type strain of B. stearothermophilus. Some properties of the...
متن کاملcloning of alkaline protease gene from bacillus subtilis 168
the aim of this study was to clone the serine alkaline protease-encoding gene from bacillus subtilis 168. this protease, which can have many applications especially in detergent, may be industrially an important enzyme. for the amplification of the gene, pcr was performed with a pair of primers specifically designed for this purpose. electrophoresis of the pcr product showed the expected band o...
متن کاملCloning of the Bacillus subtilis recE+ gene and functional expression of recE+ in B. subtilis.
By use of the Bacillus subtilis bacteriophage cloning vehicle phi 105J23, B. subtilis chromosomal MboI fragments have been cloned that alleviate the pleiotropic effects of the recE4 mutation. The recombinant bacteriophages phi 105Rec phi 1 (3.85-kilobase insert) and phi 105Rec phi 4 (3.3-kilobase insert) both conferred on the recE4 strain YB1015 resistance to ethylmethane sulfonate, methylmetha...
