Aromatic 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 کاملShikimate Pathway and Aromatic Amino Acid Biosynthesis
The shikimate pathway consists of seven enzymatic reactions whose end product chorismate is the precursor for the synthesis of the aromatic amino acids Phe, Tyr and Trp. In fungi and plants, chorismate is a precursor for many specialised metabolites (i.e. secondary metabolites) that play an important role in the plant’s interaction with its environment. The shikimate pathway and aromatic amino ...
متن کاملBiosynthesis of polybrominated aromatic organic compounds by marine bacteria
Polybrominated diphenyl ethers (PBDEs) and polybrominated bipyrroles are natural products that bioaccumulate in the marine food chain. PBDEs have attracted widespread attention because of their persistence in the environment and potential toxicity to humans. However, the natural origins of PBDE biosynthesis are not known. Here we report marine bacteria as producers of PBDEs and establish a gene...

متن کاملBiosynthesis of bacterial lipopolysaccharide. VII. Enzymatic formation of the first intermediate in biosynthesis of the O-antigen of Salmonella typhimurium.
The initial step in biosynthesis of the O-antigen of Salmonella typhimurium is the formation of a lipid-linked derivative of galactose l-phosphate, according to the reaction UDP-galactose + P-lipid ti galactose-1 -PP-lipid + UMP. The enzyme activity has been detected in the cell envelope fraction of Citrobocter strain 139 (04, 5, 12) as well as in wild type S. typhimurium strain LT-2, but is mo...
