Tryptophanamidase () is an enzyme characterised from Trichosporon cutaneum that catalyzes the hydrolysis of tryptophanamide to the amino acid, tryptophan, and ammonia:
This enzyme is a hydrolase, one acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is L-tryptophanamide amidohydrolase. Other names in common use include tryptophan aminopeptidase, and L-tryptophan aminopeptidase. It requires manganese as Mn2+.
