Cloning 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 کاملamplification, sequencing and cloning of iranian native bacillus subtilis alpha-amylase gene in saccharomyces cerevisiae
conclusions based on this similarity and our bioinformatics evaluations, this mentioned alpha-amylase gene can be expressed in s. cerevisiae as extracellular enzyme. results the presence of alpha-amylase gene in recombinant bacteria was certificated by colony-pcr method. after extraction of recombinant vector from e. coli, the competent s. cerevisiae cells were transformed using polyethylene gl...
متن کاملComparison of the alpha-amylase of Bacillus subtilis and Bacillus amyloliquefaciens.
The alpha-amylase (alpha-1,4-glucan 4-glucanohydrolase, EC 3.2.1.1) of Bacillus subtilis strain W23 is less negatively-charged than the alpha-amylase of B. amyloliquefaciens strain F, as determined by electrophoretic mobility in polyacrylamide gel at pH 8.6. The alpha-amylase of strain W23 is immunologically unrelated to the alpha-amylase of strain F, as judged by lack of cross-reaction in Ouch...
متن کاملPURIFICATIO N OF ALPHA-AMYLASE FROM BACILLUS SUBTILlS LINE # 1024 WITH ATCC 465
Alpha-amylase E.C.3.2.1.1. (1,4 glucan, 4 glucanohydrolase) can be obtained from salivary glands, pancreas and microorganisms such as Pseudomonas and Asperigllus, as well as muscles and ovarian tubes.1.2 Alpha-amylase from Bacillus Subtilis #1024(A TCC 465)* was purified with a highest degree of purity in our laboratory (31.59 U/mg). The extracellular alpha-amylase was subjected to differe...
متن کاملCloning and expression of an alpha-amylase gene from Streptomyces thermoviolaceus CUB74 in Escherichia coli JM107 and S. lividans TK24.
A gene coding for a thermostable extracellular alpha-amylase, carried by a 5.7 kb BamHI chromosomal DNA fragment isolated from Streptomyces thermoviolaceus strain CUB74, was cloned into Escherichia coli JM107 using, as a cloning vector, the high-copy-number plasmid pUC8. E. coli containing a recombinant plasmid pQR300 expressed the amylase gene and exported the enzyme into the periplasmic space...
