Purification and Chemical Characterization of Malate Dehydrogenase of Bacillus subtilis
In an attempt to elucidate the relationships between some pyridine nucleotide-dependent dehydrogenases in Bacillus subtilis, such as alanine dehydrogenase, malate dehydrogenase, lactate dehydrogenase, and glutamate dehydrogenase, these enzymes are being purified and characterized with respect to their chemical, serological, and enzymic properties. In two previous papers (1, 2), the purification...
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 کاملCcpA-dependent regulation of Bacillus subtilis glutamate dehydrogenase gene expression.
The Bacillus subtilis rocG gene, encoding catabolic glutamate dehydrogenase, was found to be subject to direct CcpA-dependent glucose repression. The effect of CcpA required the presence of both the HPr and Crh proteins. The primary CcpA binding site was identified by mutational analysis and DNase I footprinting. In the absence of inducers of the Roc pathway, rocG was still expressed at a low l...
متن کاملCharacterization of the developmentally regulated Bacillus subtilis glucose dehydrogenase gene.
The DNA sequence of the structural gene for glucose dehydrogenase (EC 1.1.1.47) of Bacillus subtilis was determined and comprises 780 base pairs. The subunit molecular weight of glucose dehydrogenase as deduced from the nucleotide sequence is 28,196, which agrees well with the subunit molecular weight of 31,500 as determined from sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The se...
متن کاملRegulation of glutamate dehydrogenase in Bacillus subtilis.
The activity of the nicotinamide adenine dinucleotide-dependent glutamate dehydrogenase in Bacillus subtilis was influenced by the carbon source, but not the nitrogen source, in the growth medium. The highest specific activity for this enzyme was found when B. subtilis was grown in a minimal or rich medium that contained glutamate as the carbon source. It is proposed that glutamate dehydrogenas...
