Escherichia coli grew anaerobically on L-malate only in the presence of H2; 91% of the L-malate utilized was converted to succinate. Anaerobically isolated membrane vesicles catalyzed the reduction of fumarate with H2 and contained a b-type cytochrome. Cytochrome c552 was present in the "periplasmic space."
大肠杆菌仅在有氢气存在的情况下才能以L-苹果酸为底物进行厌氧生长;所利用的L-苹果酸中有91%被转化为琥珀酸。厌氧分离得到的膜囊泡能催化氢气还原富马酸,并含有一种b型细胞色素。细胞色素c552存在于“周质空间”中。
