Abstract
Summary: Results of feeding experiments in Streptomyces amakusaensis with (22, 3R)-[3- 2H,]-and (22, 3g)-[2, 3-2H2]-serine show that the F-formyl group in tuberin (1) is formed from C-3 of serine via tetrahydrofolate-linked intermediates with retention of the 3-pro-S--proton; retention is only partially stereospecific. The relevance to tetrahydrololate metabolism is discussed.
