| Abstract: | Summary
l-Valyl-l-leucine-U-14C,l-valyl-l-proline-U-14C-lactam andl-leucyl-l-proline-U-14C-lactam were administered to submerged cultures of an ergotoxine-mixture-producing strain ofClaviceps purpurea. The added dipeptides were split by the fungus into the corresponding amino acids prior to incorporation. Apparently dipeptides are no immediate precursors for the peptide side-chain of ergotoxinealkaloids. |
