| Hazard Information | Back Directory | [Description]
Aminoacylase-1 (EC 3.5.1.14) is a homodimeric zinc-binding metalloenzyme. A cytosolic enzyme with a wide range of tissue expression, it cleaves acylated L-amino acids (except L-aspartate) into L-amino acids and an acyl group. L-aspartate derivatives are cleaved by aminoacylase-2 (aspartoacylase). Aminoacylase-1 is the most abundant of the aminoacylases, a class of enzymes involved in hydrolysis of N-acetylated proteins. | [Chemical Properties]
Light red or light yellow lyophilized powder, soluble in water, with an optimal pH of 7.0-7.5 (porcine kidney, amylase) or 7-8 (rice aspergillus). Stability: The pure enzyme can be stored for long periods without loss of activity after lyophilization; the crude enzyme solution can be refrigerated for 1-2 days after adding toluene. The crude enzyme preparation is stable at 5°C. At a pH of 7, the enzyme solution maintains activity for 60 minutes at 70°C. When the pH is below 5, it rapidly loses activity at 70°C. Substrate chemical structure requirements: Monocarboxylic amino acids; the amino group on the α-carbon atom of the amino acid is acylated, and different acylation groups result in different hydrolysis rates. Enzymes from different sources have different substrate chemical structure specificities. Enzyme reaction: N-acylated L-amino acid + H??O═ fatty acid anion + L-amino acid. | [Uses]
Acylase I from porcine kidney has been used to study the acylase I-catalyzed deacetylation of various S-alkyl-N-acetyl-L-cysteines and their carbon and oxygen analogues . Acylase I may be useful to catalyze N-acetyl amino acids to enantiomerically pure L-amino acids . | [Application]

Aminoacylases (N-acyl-L-amino acid amidohydrolases; EC 3.5.1.14) are widely found in animals, plants and microorganisms. The primary function of these enzymes is to remove acyl residues from N-acetylated amino acids although they may also be capable of hydrolysing carboxylic acid amides to fatty acid anions and L-amino acids. Although the catalytic mechanism of aminoacylases has been known for decades, the physiological role of these enzymes is still poorly understood. Activities of a similar nature, however, have been found in certain carboxypeptidases, aminopeptidases and dipeptidases. It could be therefore suggested that aminoacylases have a role to play in protein/peptide turnover. | [General Description]
Acylase I belongs to the aminoacylase family of enzymes. | [Biological Activity]
Acylase I catalyzes the deacetylation of N-acetyl-L-cysteine and S-alkyl-N-acetyl-L-cysteines. n-Butylmalonic acid is an inhibitor of acylase I. S-alkyl-N-acetyl-L-cysteines with short (C0-C3) and unbranched S-alkyl substituents have been found to be good acylase I substrates. | [Biochem/physiol Actions]

Aminoacylase is a metallo-enzyme that needs Zinc (Zn2+) as a cofactor to function. The Zinc ions inside of aminoacylase are each coordinated to histidine, glutamate, aspartate, and water. The Zinc ion polarizes the water, facilitating its deprotonation by a nearby basic residue. The negatively charged hydroxide ion is nucleophilic and attacks the electrophilic carbonyl carbon of the substrate's acyl group.The exact mechanism after this point is unknown, with one possibility being that the carbonyl then reforms, breaks the amide bond, and forms the two products. At some point in the mechanism, another water molecule enters and coordinates with Zinc, returning the enzyme to its original state.
The nucleophilic attack by water is the rate-limiting step of aminoacylase's catalytic mechanism. This nucleophilic attack is reversible while the subsequent steps are fast and irreversible. This reaction sequence is an example of Michaelis–Menten kinetics, allowing one to determine KM, Kcat, Vmax, turnover number, and substrate specificity through classic Michaelis-Menten enzyme experiments. The second and third forward steps cause the formation and release of the reaction's products. |
