Regulation of aromatic amino acid biosynthesis in Bacillus subtilis 168. I. Evidence for and characterization of a trifunctional enzyme complex.
A bifunctional enzyme, consisting of 3-deoxy-n-arabinoheptulosonate 7-phosphate synthetase and chorismate mutase, has been purified to homogeneity from Bacillus subtilis. Ultracentrifugation revealed a single symmetrical peak of protein. A single protein band also was observed when the homogeneous preparation was subjected to polyacrylamide gel electrophoresis in the presence of sodium dodecyl ...
متن کاملAromatic Amino Acid Biosynthesis 529 Regulation of Aromatic Amino Acid Biosynthesis in Gamma-Proteobacteria
Computational comparative techniques were applied to analysis of the aromatic amino acid regulons in gamma-proteobacteria. This resulted in characterization of the TrpR and TyrR regulons in the genomes of Yersinia pestis, Haemophilus influenzae, Vibrio cholerae and other bacteria and identification of new members of the PhhR regulon in the genome of Pseudomonas aeruginosa. Candidate attenuators...
متن کاملAn enzyme common to histidine and aromatic amino acid biosynthesis in Bacillus subtilis.
Two transaminases exist for tyrosine and phenylalanine synthesis in Bacillus subtilis. One enzyme is also responsible for the transamination of imidazole acetol phosphate to histidinol phosphate, an obligatory reaction in the synthesis of histidine. The gene involved in the synthesis of this enzyme lies in the middle of a cluster of genes, all of which are concerned with the synthesis of the ar...

متن کاملTranscriptional organization and posttranscriptional regulation of the Bacillus subtilis branched-chain amino acid biosynthesis genes.
In Bacillus subtilis, the genes of the branched-chain amino acids biosynthetic pathway are organized in three genetic loci: the ilvBHC-leuABCD (ilv-leu) operon, ilvA, and ilvD. These genes, as well as ybgE, encoding a branched-chain amino acid aminotransferase, were recently demonstrated to represent direct targets of the global transcriptional regulator CodY. In the present study, the transcri...
