We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

CRYSTAL STRUCTURE OF CLEAVED EQUINE LEUCOCYTE ELASTASE INHIBITOR DETERMINED AT 1.95 ANGSTROMS RESOLUTION

Overview

The crystal structure of active-site cleaved equine leucocyte elastase, inhibitor, a member of the serpin superfamily, has been solved and refined, to a crystallographic R-factor of 17.6% at 1.95 A resolution. Despite, being an intracellular inhibitor with rather low sequence homology of 30%, to human alpha 1-antichymotrypsin and alpha 1-proteinase inhibitor, the, three-dimensional structures are very similar, with deviations only at the, sites of insertions and few mobile secondary structure elements. The, better resolution in comparison with the structures of other cleaved, serpins allows a more precise description of the so-called R-state of the, serpins.
