MOLECULAR 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 کاملMethionine regeneration and aminotransferases in Bacillus subtilis, Bacillus cereus, and Bacillus anthracis.
The conversion of ketomethiobutyrate to methionine has been previously examined in a number of organisms, wherein the aminotransferases responsible for the reaction have been found to be members of the Ia subfamily (L. C. Berger, J. Wilson, P. Wood, and B. J. Berger, J. Bacteriol. 183:4421-4434, 2001). The genome of Bacillus subtilis has been found to contain no subfamily Ia aminotransferase se...
متن کاملTransduction in Bacillus cereus and Bacillus anthracis.
A phage, designated CP-51, that carries out generalized transduction in Bacillus cereus and B. anthracis, has recently been isolated from soil. Transducing phages for members of the genus Bacillus have been described previously for B. subtilis and B. licheniformis (2-6). Those that have been best characterized are PBS-1 for B. subtilis (4) and SP-10 and SP-15 for both B. subtilis and B. licheni...
متن کاملUnrelatedness of Bacillus amyloliquefaciens and Bacillus subtilis.
Eight strains of highly amylolytic, sporeforming bacilli (hereafter referred to as Bacillus amyloliquefaciens) were compared with respect to their taxonomic relationship to B. subtilis. The physiological-biochemical properties of these two groups of organisms showed that B. amyloliquefaciens differed from B. subtilis by their ability to grow in 10% NaCl, characteristic growth on potato plugs, i...
متن کاملExpression in Bacillus subtilis of the 51- and 42-kilodalton mosquitocidal toxin genes of Bacillus sphaericus.
A 3,080-base-pair KpnI-HindIII DNA fragment from Bacillus sphaericus 2362 coding for 51- and 42-kilodalton mosquitocidal proteins was cloned into Bacillus subtilis DB104 by using the vector pUB18. In B. subtilis these proteins were not detected during vegetative growth but were expressed during sporulation at levels comparable to those found in B. sphaericus.
