Description
N(alpha)-methyl-L-tryptophan is a N-methyl-L-alpha-amino acid that is the N(alpha)-methyl derivative of L-tryptophan. It has a role as an Escherichia coli metabolite. It is a L-tryptophan derivative and a N-methyl-L-alpha-amino acid. It is a tautomer of a N(alpha)-methyl-L-tryptophan zwitterion.
N-Methyltryptophan is a metabolite found in or produced by Escherichia coli (strain K12, MG1655).
Abrine has been reported in Daphnia pulex, Aspergillus fumigatus, and other organisms with data available.
