EC Tree
IUBMB Comments
This enzyme is found in animals and is involved in the hydrolysis of N-acylated or N-acetylated amino acids (except L-aspartate). It preferentially deacetylates Nalpha-acetylated aromatic amino acids and mercapturic acids (S-conjugates of N-acetyl-L-cysteine) that are usually not deacetylated by EC 3.5.1.14, N-acyl-aliphatic-L-amino acid amidohydrolase. The enzyme is significantly activated by Co2+ and Ni2+ . Some bacterial aminoacylases demonstrate substrate specificity for both EC 3.5.1.14 and EC 3.5.1.114. cf. EC 3.5.1.14, N-acyl-aliphatic-L-amino acid amidohydrolase and EC 3.5.1.15, aspartoacylase.

N-acyl-aromatic-L-amino acid amidohydrolase (carboxylate-forming)
This enzyme is found in animals and is involved in the hydrolysis of N-acylated or N-acetylated amino acids (except L-aspartate). It preferentially deacetylates Nalpha-acetylated aromatic amino acids and mercapturic acids (S-conjugates of N-acetyl-L-cysteine) that are usually not deacetylated by EC 3.5.1.14, N-acyl-aliphatic-L-amino acid amidohydrolase. The enzyme is significantly activated by Co2+ and Ni2+ [3]. Some bacterial aminoacylases demonstrate substrate specificity for both EC 3.5.1.14 and EC 3.5.1.114. cf. EC 3.5.1.14, N-acyl-aliphatic-L-amino acid amidohydrolase and EC 3.5.1.15, aspartoacylase.

LITERATURE
Ni2+
Co2+ and to a lesser extent Ni2+ increases activity several times in comparison with intact wild type AA3. Co2+ drastically increases the rate of deacetylation of N-acetyl-1,2-dichlorovinyl-L-cysteine and significantly increased the toxicity of Ac-DCVC in the HEK293T cells expressing wt-AA3. Aminoacylase 3 is a metalloenzyme significantly activated by Co2+ and Ni2+
