从布氏锥虫的血流形式的膜中纯化了一种蛋白质。纯化的材料含有一个单一的多肽链的分子量为67千道尔顿,判断由十二烷基硫酸钠-聚丙烯酰胺凝胶电泳;在“天然”条件下,它通过Sephacryl S-300柱迁移具有类似的分子量。纯化的蛋白质催化电子从sn-甘油3-磷酸转移到氧气,随后形成水。由纯化的酶到O2的电子转移依赖于低浓度的介体吩嗪硫酸甲酯的存在。这种蛋白质显然是主要的膜结合的sn-甘油-3-磷酸脱氢酶,但它也有一些特征,提示锥虫替代氧化酶的活动。
A protein has been purified from the membranes of bloodstream forms of Trypanosoma brucei brucei. The purified material contained a single polypeptide chain of molecular mass 67 kilodaltons as judged by sodium dodecyl sulfate-polyacrylamide gel electrophoresis; under "native" conditions it migrated through a Sephacryl S-300 column with a similar molecular mass. The purified protein catalysed electron transfer from sn-glycerol 3-phosphate to oxygen with the subsequent formation of water. Electron transfer by the purified enzyme to O2 was dependent on the presence of low concentrations of the mediator phenazine methosulfate. This protein is clearly the major membrane-bound sn-glycerol-3-phosphate dehydrogenase, but it also has some characteristics suggestive of the trypanosome alternative oxidase activities.
