Fe(III)-EDTA reductase was purified from Bacillus sp. B-3 isolated as a Fe(III)-EDTA-degrading bacterium. The purified enzyme showed a single protein band corresponding to a molecular mass of 19 kDa on SDS-PAGE, and had FMN as cofactor. It was alkali-thermostable. Its N-terminal amino acid sequence was identical with that of NADPH azoreductase from several species of Bacillus.
从作为铁(III)-乙二胺四乙酸(EDTA)降解菌分离出的芽孢杆菌属B-3中纯化出铁(III)-EDTA还原酶。纯化后的酶在十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)上显示出一条对应于分子量为19 kDa的单一蛋白条带,并且以黄素单核苷酸(FMN)作为辅因子。它具有碱热稳定性。其N端氨基酸序列与几种芽孢杆菌属的NADPH偶氮还原酶的序列相同。
