The catalytic mechanism of arylamine N-acetyltransferase has been proposed to involve Cys-His-Asp as its catalytic triad. Thiolsubtilisin, a chemically modified enzyme that has a catalytic triad of Cys-His-Asp at the active site, mimics the catalysis of arylamine N-acetyltransferase, serotonin N-acetyltransferase
