Metabolite Identification
Common NameN-acetyl-D-methionine
DescriptionN-acetyl-D-methionine is a member of the class of N-acylated amino acids, specifically an acetylated derivative of the amino acid methionine. Its chemical structure features an acetyl group attached to the nitrogen atom of the methionine backbone, influencing its biochemical properties and interactions. N-acetyl-D-methionine is involved in various metabolic pathways, particularly in the context of amino acid metabolism. For instance, the disruption of the HPA3 gene, which encodes the enzyme d-amino acid-N-acetyltransferase, leads to the accumulation of d-methionine and the absence of N-acetyl-D-methionine production (PMID:31478186 ). The enzyme exhibits high activity toward N-acetyl-D-methionine compared to other aromatic and hydrophobic N-acetylamino acids (PMID:29509381 ). Additionally, it has been noted that N-acetyl-D-methionine can be hydrolyzed by N-acyl-d-amino acid amidohydrolase, producing L-methionine and acetic acid (PMID:9699991 ). Kinetic studies have revealed various Michaelis constants (Km) for N-acetyl-D-methionine, indicating its role as a substrate for enzymatic reactions (PMIDs:1368943, 7766084). Overall, N-acetyl-D-methionine serves as a significant compound in metabolic processes involving amino acid modification and utilization.
