Acylamino-acid-releasing enzyme is an enzyme that in humans is encoded by the APEH gene. [5] [6]
This gene encodes the enzyme acylpeptide hydrolase, which catalyzes the hydrolysis of the terminal acetylated amino acid preferentially from small acetylated peptides. The acetyl amino acid formed by this hydrolase is further processed to acetate and a free amino acid by an aminoacylase. This gene is located within the same region of chromosome 3 (3p21) as the aminoacylase gene, and deletions at this locus are also associated with a decrease in aminoacylase activity. The acylpeptide hydrolase is a homotetrameric protein of 300 kDa with each subunit consisting of 732 amino acid residues. It can play an important role in destroying oxidatively-damaged proteins in living cells. Deletions of this gene locus are found in various types of carcinomas, including small-cell lung carcinoma and renal cell carcinoma. [6]
Aldolase A, also known as fructose-bisphosphate aldolase, is an enzyme that in humans is encoded by the ALDOA gene on chromosome 16.
Aspartoacylase is a hydrolase enzyme that in humans is encoded by the ASPA gene. ASPA is responsible for catalyzing the deacylation of N-acetyl-l-aspartate (N-acetylaspartate) into aspartate and acetate. It is a zinc-dependent hydrolase that promotes the deprotonation of water to use as a nucleophile in a mechanism analogous to many other zinc-dependent hydrolases. It is most commonly found in the brain, where it controls the levels of N-actetyl-l-aspartate. Mutations that result in loss of aspartoacylase activity are associated with Canavan disease, a rare autosomal recessive neurodegenerative disorder.
Eukaryotic translation initiation factor 5A-1 is a protein that in humans is encoded by the EIF5A gene.
Cathepsin L1 is a protein that in humans is encoded by the CTSL1 gene.
Protein-glutamine gamma-glutamyltransferase E is an enzyme that in humans is encoded by the TGM3 gene.
Anion exchange protein 2 (AE2) is a membrane transport protein that in humans is encoded by the SLC4A2 gene. AE2 is functionally similar to the Band 3 Cl−/HCO3− exchange protein.
Hydroxyacylglutathione hydrolase, mitochondrial is an enzyme that in humans is encoded by the HAGH gene.
Dimethylaniline monooxygenase [N-oxide-forming] 1 is an enzyme that in humans is encoded by the FMO1 gene.
Protein-L-isoaspartate(D-aspartate) O-methyltransferase is an enzyme that in humans is encoded by the PCMT1 gene.
Sialic acid-binding Ig-like lectin 7 is a protein that in humans is encoded by the SIGLEC7 gene. SIGLEC7 has also been designated as CD328.
Dipeptidase 1 (DPEP1), or renal dipeptidase, is a membrane-bound glycoprotein responsible for hydrolyzing dipeptides. It is found in the microsomal fraction of the procine kidney cortex. It exists as a disulfide-linked homodimer that is glygosylphosphatidylinositol (GPI)-anchored to the renal brush border of the kidney. The active site on each homodimer is made up of a barrel subunit with binuclear zinc ions that are bridged by the Gly125 side-chain located at the bottom of the barrel.
