the two isomers 2, 3 of the mono coenzyme A ester of o-succinylbenzoic acid (1, OSB, i.e. 4-(2-carboxyphenyl)-4-oxobutanoic acid) and enzymic conversion of 3, to 1,4-dihydroxy-2-naphthoic acid 7 shows that as opposed to previous assumptions the “aliphatic” rather than the “aromatic” carboxyl group in o-succinylbenzoic acid 1 is activated during vitamin K2 biosynthesis in Escherichia coli and Mycobacterium
单辅酶的两个异构体2、3的合成邻琥珀酰苯甲酸的酯(1,OSB,即4-(2-羧基苯基)-4-氧代丁酸),并将3酶促转化为1,4-二羟基-2-萘甲酸7与以前的假设相反,在大肠杆菌和phlei分枝杆菌中维生素K 2的生物合成过程中,邻琥珀酰苯甲酸1中的“脂肪族”羧基而不是“芳香族”羧基。
