The distribution of 10-formyltetrahydrofolate synthetase, which activates formate for use as a one-carbon donor in a variety of biosynthetic reactions, was determined for a variety of eubacteria. Organisms from several genera were found to lack detectable synthetase activity; however, all organisms tested were found to contain 5,10-methylenetetrahydrofolate dehydrogenase activity.
测定了多种真细菌中10-甲酰四氢叶酸合成酶的分布情况,该酶可激活甲酸,使其在多种生物合成反应中用作一碳供体。发现几个属的生物缺乏可检测到的合成酶活性;然而,所有测试的生物均含有5,10-亚甲基四氢叶酸脱氢酶活性。
