  • Title: Oversynthesis of diacetyl and acetoin in a riboflavin deficient mutant of yeast.
    Author: Nakajima K, Saito A.
    Journal: Int J Vitam Nutr Res; 1987; 57(3):279-83. PubMed ID: 3316092.
    Abstract:
    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.
