En homolog grupp av endogena cysteinproteinashämmare. Det finns fyra distinkta familjer inom cystatinsuperfamiljen: cystatin B eller stefiner; cystatin C eller post-gammaglobulin; äggvita eller hönscystatin; samt kininogent cystatin. Cystatinerna hämmar de flesta cysteinendopeptidaser av papaintyp och andra peptidaser med en sulfhydrylgrupp vid den aktiva platsen.
A homologous group of endogenous CYSTEINE PROTEINASE INHIBITORS. The cystatins inhibit most CYSTEINE ENDOPEPTIDASES such as PAPAIN, and other peptidases which have a sulfhydryl group at the active site.
