peptidyl-aspartic acid 3-dioxygenase activity
Definition
Target type: molecularfunction
Catalysis of the reaction: protein L-aspartate + 2-oxoglutarate + O2 = protein 3-hydroxy-L-aspartate + succinate + CO2. [PMID:1378441, PMID:1856229, RHEA:11508]
Peptidyl-aspartic acid 3-dioxygenase activity is a catalytic activity that involves the oxidation of a specific aspartate residue within a peptide chain. This reaction introduces a hydroxyl group (OH) at the C3 position of the aspartate residue, converting it to a 3-hydroxyaspartate. The reaction requires molecular oxygen (O2) as a co-substrate, and in many cases, it also depends on the presence of a metal ion, typically iron. The enzyme responsible for this activity, known as peptidyl-aspartic acid 3-dioxygenase (PAD), is a non-heme diiron enzyme. PAD plays a crucial role in the biosynthesis of various secondary metabolites, including antibiotics and siderophores. The hydroxylation of aspartate by PAD can significantly alter the chemical properties of the peptide, impacting its function and interactions with other molecules. Furthermore, the 3-hydroxyaspartate residue can serve as a precursor for further enzymatic modifications, leading to the generation of diverse bioactive molecules.'
