Tryptophan (Try) metabolism of Arthrobacter sp. was examined. The inducibility of the Try oxidizing enzyme system seems to be correlated with that of the indole‐3‐acetic acid (IAA) oxidizing enzyme system. Try is metabolized to IAA via indole‐3‐pyruvic acid (Ip) and indole‐3‐acetaldehyde (IAAId). Indole‐3‐acetamide (IAm) is formed as a product of Try oxidation. Exogenous IAm, indole‐3‐acetonitrile (IAN) and tryptamine are not oxidized by Try‐induced cells.
