Oversynthesis of diacetyl and acetoin in a riboflavin deficient mutant of yeast

Oversynthesis of diacetyl and acetoin in a riboflavin deficient mutant of yeast

International Journal for Vitamin and Nutrition Research. Internationale Zeitschrift für Vitamin- und Ernahrungsforschung. Journal International de Vitaminologie et de Nutrition 57(3): 279-283

The relations of diacetyl and acetoin to flavinogenesis were studied using a variety of the riboflavin deficient mutants of yeast. The results obtained indicated that only the mutant N189-10A, which have a defect in the pathway positioned next to the nucleotide precursor, guanosine triphosphate (GTP), produces prodigeous amounts of diacetyl and acetoin among the mutants and the wild strain used. A close relation of diacetyl and acetoin to riboflavin formation at their substrate level or regulator level was discussed.
