Abstract excerpt

The activity of 2,5-diamino-6-hydroxy-4-ribosylaminopyrimidine-5'-phosphate reductase, an enzyme of the second step of flavinogenesis, was studied in the yeast Pichia guilliermondii using a new fluorimetric technique. The activity of the enzyme was found in extracts of the wild-type strain and the genotype rib mutants but not in extracts of the FM 1-4 (rib 2) mutant. Interallelic complementation was revealed in...
