Chemical structure of Pyr-Phe-Leu-pNA

GA23427

Pyr-Phe-Leu-pNA

Also known as (2S)-N-[(2S)-1-[[(2S)-4-methyl-1-(4-nitroanilino)-1-oxopentan-2-yl]amino]-1-oxo-3-phenylpropan-2-yl]-5-oxopyrrolidine-2-carboxamide

Chromogenic substrate for thiol proteinases from plants (caricain, papain, ficin, and bromelain) and from mammalian brain (cathepsin B)· pEFL-pNA is also cleaved by a serine carboxypeptidase (HlSCP1) identified in the midgut of the hard tick Haemaphysalis longicornis, which was shown to process hemoglobin
