The electron-transfer complex of BphA3, a Rieske-type [2Fe-2S] ferredoxin, and BphA4, a NADH-dependent ferredoxin reductase, was crystallized using the sitting-drop vapour-diffusion method under anaerobic conditions. The obtained crystals were analyzed by SDS-PAGE, which showed that they contained both BphA3 and BphA4. The crystals belong to space group P2(1), with unit-cell parameters a = 60.60, b = 173.72, c = 60.98 A, beta = 115.8 degrees, and diffracted to a resolution of 1.9 A.
在厌氧条件下,使用坐滴气相扩散法使BphA3(一种Rieske型[2Fe-2S]铁氧化还原蛋白)与BphA4(一种依赖NADH的铁氧化还原蛋白还原酶)的电子转移复合物结晶。通过SDS-PAGE对获得的晶体进行分析,结果表明晶体中同时含有BphA3和BphA4。这些晶体属于空间群P2(1),晶胞参数为a = 60.60、b = 173.72、c = 60.98 Å,β = 115.8°,衍射分辨率为1.9 Å。
