Abstract

Ferredoxin-NADP(+) oxidoreductase encoded by Bacillus subtilis yumC has been purified and successfully crystallized in complex with NADP(+) in two forms. Diffraction data from crystals of these two forms were collected at resolutions of 1.8 and 1.9 A. The former belonged to space group P2(1)2(1)2, with unit-cell parameters a = 63.90, b = 135.72, c = 39.19 A, and the latter to space group C2, with unit-cell parameters a = 207.47, b = 64.85, c = 61.12 A, beta = 105.82 degrees. The initial structure was determined by the molecular-replacement method using a thioredoxin reductase-like protein as a search model.

摘要

枯草芽孢杆菌yumC编码的铁氧化还原蛋白-NADP(+)氧化还原酶已被纯化,并成功以两种形式与NADP(+)形成复合物结晶。这两种形式晶体的衍射数据在1.8和1.9埃分辨率下收集。前者属于空间群P2(1)2(1)2,晶胞参数a = 63.90,b = 135.72,c = 39.19埃,后者属于空间群C2,晶胞参数a = 207.47,b = 64.85,c = 61.12埃,β = 105.82°。初始结构通过分子置换法,以硫氧还蛋白还原酶样蛋白作为搜索模型确定。
