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 کاملRegulation of aromatic amino acid biosynthesis in higher plants. Properties of an aromatic amino acid-sensitive chorismate mutase (CM-1) from mung bean.
Etiolated mung bean seedlings were examined for chorismate mutase activity. Evidence for the occurrence of two forms of the enzyme (designated CM-1 and CM-2) was obtained by ammonium sulfate fractionation, anion exchange cellulose chromatography, and isoelectric focusing. The two forms showed distinctly different properties, as CM-1 was inhibited by phenylalanine and tyrosine and activated by t...

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 کاملIntroducing aromatic amino acid hydroxylases from plants.
In humans, a deficiency in Phe hydroxylase activity results in phenylketonuria, a metabolic disorder that is characterized by the accumulation of Phe. Phe hydroxylase belongs to the iron-containing aromatic amino acid hydroxylase (AAH) family, whose members catalyze the hydroxylation of Phe, Trp, or Tyr in a reaction that depends on the donation of electrons by tetrahydropterin (reviewed in Fit...
