Abstract :
A soluble form of the killer factor and prohormone-processing carboxypeptidase, "Kex1 delta p," from Saccharomyces cerevisiae, has been crystallized in 17-22% poly(enthylene glycol) methyl ether (average M(r) = 5,000), 100 mM ammonium acetate, 5% glycerol, pH 6.5, at 20 degrees C. A native data set (2.8 A resolution) and four derivative data sets (3.0-3.2 A resolution) were collected at the Photon Factory (lambda = 1.0 A). The crystals belong to space group P2(1)2(1)2(1) with a =56.6 A, b = 84.0 A, c = 111.8 A. Freezing a Kex1 delta p crystal has facilitated the collection of a 2.4-A data set using a rotating anode source (lambda = 1.5418 A). Molecular replacement models have been built based on the structures of wheat serine carboxypeptidase (CPDW-II; Liao DI et al., 1992, Biochemistry 31:9796-9812) and yeast carboxypeptidase Y. |
