Abstract
Cells of E.rcherichia coli vitamin B,,/methionine auxotroph have been shown to
possess an ability to convert tetrahydrofolic acid to N'-formyltetrahydrofolic
acid. Optimum conditions for this conversion have been worked out. It was
shown that serine is a better one-carbon donor than formate. Vitamin BI'
suppresses conversion of tetrahydrofolic acid to N'-formyltetrahydrofolic acid
when serine is used as one-carbon donor and stimulates it when the one-carbon
donor is formate. Vitamin B" antagonists do not have any effect on tbis
conversion.
