BRITE hierarchy
Sysname
phthalyl-amide amidohydrolase
Reaction(IUBMB)
a phthalylamide + H2O = phthalic acid + a substituted amine [RN:R05167]
Reaction(KEGG)
Substrate
phthalylamide [CPD:C06374];
H2O [CPD:C00001]
Product
phthalic acid;
substituted amine [CPD:C00706]
Comment
In the entry, "phthalyl" is used to mean "2-carboxybenzoyl". The enzyme from Xanthobacter agilis hydrolyses phthalylated amino acids, peptides, beta-lactams, aromatic and aliphatic amines. The substituent on nitrogen may be an alkyl group, but may also be complex, giving an amino acid or peptide derivative. Substitutions on the phthalyl ring include 6-F, 6-NH2, 3-OH, and a nitrogen in the aromatic ring ortho to the carboxy group attached to the amine. No cofactors are required
