HUMAN TACE G13 MUTANT
|
OverviewOverview
Human angiotensin-converting enzyme is an important drug target for which, little structural information has been available until recent years. The, slow progress in obtaining a crystal structure was due to the problem of, surface glycosylation, a difficulty that has thus far been overcome by the, use of a glucosidase-1 inhibitor in the tissue culture medium. However, the prohibitive cost of these inhibitors and incomplete glucosidase, inhibition makes alternative routes to minimizing the N-glycan, heterogeneity desirable. Here, glycosylation in the testis isoform (tACE), has been reduced by Asn-Gln point mutations at N-glycosylation sites, and, the crystal structures of mutants having two and four intact sites have, been solved to 2.0 A and 2.8 A, respectively. Both mutants show close, ... [(full description)]
