4-aminobenzoate synthase

UniProtKB accession:  O84616

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in de novo para-aminobenzoate (PABA) biosynthesis (PubMed:23972426, PubMed:32967910, PubMed:36122239). Acts as a self-sacrificing or 'suicide' enzyme that utilizes its own active site tyrosine residue(s) as the substrate for PABA synthesis (PubMed:32967910, PubMed:36122239). The side chain of the tyrosine residue is released from the protein backbone via cleavage of the C(alpha)-C(beta) bond, leaving a glycine in place of the original tyrosine residue (PubMed:32967910, PubMed:36122239). Reaction requires O(2) and a reduced dimetal cofactor (PubMed:32967910, PubMed:36122239).
