Identification
Name:N-Methyltryptophan
DescriptionN-methyltryptophan is a member of the chemical class known as Alpha Amino Acids and Derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group. N-Methyltryptophan is catabolized by MTOX. N-Methyltryptophan oxidase (MTOX) is a flavoenzyme that catalyzes the oxidative demethylation of N-methyl-L-tryptophan and other N-methyl amino acids, including sarcosine, which is a poor substrate. (PMID 11170472) MTOX is converted to a 2-electron reduced form upon anaerobic reaction with N-methyl-L-tryptophan, sarcosine, or the carbinolamine formed with L-tryptophan and formaldehyde. (PMID 11170473)
