CRYSTAL STRUCTURE OF THE COMPLEX OF APOPAIN WITH THE TETRAPEPTIDE ALDEHYDE INHIBITOR AC-DEVD-CHO
Overview
Cysteine proteases related to mammalian interleukin-1 beta converting, enzyme (ICE) and to its Caenorhabditis elegans homologue, CED-3, play a, critical role in the biochemical events that culminate in apoptosis. We, have determined the three-dimensional structure of a complex of the human, CED-3 homologue CPP32/apopain with a potent tetrapeptide-aldehyde, inhibitor. The protein resembles ICE in overall structure, but its S4, subsite is strikingly different in size and chemical composition. These, differences account for the variation in specificity between the ICE- and, CED-3-related proteases and enable the design of specific inhibitors that, can probe the physiological functions of the proteins and disease states, with which they are associated.
