Ac-Trp-Glu-His-Asp-AMC
Also known as (4S)-4-[[(2S)-2-acetamido-3-(1H-indol-3-yl)propanoyl]amino]-5-[[(2S)-1-[[(2S)-3-carboxy-1-[(4-methyl-2-oxochromen-7-yl)amino]-1-oxopropan-2-yl]amino]-3-(1H-imidazol-5-yl)-1-oxopropan-2-yl]amino]-5-oxopentanoic acid
With a kcat/Km of 3·3 · 10? M?¹s?¹ the fluorogenic caspase-1 substrate Ac-WEHD-AMC is cleaved 50-fold more efficiently than I-1630· This result indicates that the optimal tetrapeptide recognition sequence for caspase-1 is Trp-Glu-His-Asp and not Tyr-Val-Ala-Asp
