INCORPORATION OF RADIOACTIVE CARBON INTO A PTERIDINE OF A BLUE-GREEN ALGA

Abstract
A labeled pteridine has been obtained from Anacystis nidulans during photosynthesis in the presence of C14O2. After acid hydrolysis, this pteridine yielded unlabeled biopterin and a labeled and as yet unidentified fragment. The possible significance of this and related compounds in photosynthetic metabolism is discussed.
