Abstract excerpt

The nature of riboflavin precursors was studied in the yeast Pichia guilliermondii. By means of mutants with blocked GMP-synthetase the purine precursors of riboflavin were shown to belong to guanylic compounds. Accumulation of 2,4,5-triamino-6-oxypyrimidine, 2,5-diamino-6-oxy-4-ribitylaminopyrimidine, 2,6-dioxy-5-amino-4-ribitylaminopyrimidine (DOARAP) and 6,7-dimethyl-8-ribityllumasine occurs in the...
