ABSTRACT
Sake yeasts have a range of brewing characteristics that are particularly beneficial for sake making including high ethanol fermentability, high proliferative capacity at low temperatures, lactic acid tolerance, and high ester productivity. On the other hand, sake yeasts also accumulate a diverse range of functional components. For example, significantly greater accumulation of S-adenosylmethionine (SAM), a compound that plays important regulatory roles in a range of biological processes as a major donor of methyl groups, occurs in sake yeasts compared to other microorganisms. Significantly greater accumulation of folate, a bioactive water-soluble vitamin (vitamin B9), also occurs in sake yeasts compared to laboratory yeasts, and the methyl group on SAM is supplied by folate. Accordingly, fully characterizing 'sake yeast identity' requires detailed understanding of the mechanisms underlying both the nutritional characteristics (functional components) and the brewing characteristics in sake yeasts. Therefore, this mini-review focuses on the accumulation of SAM and folate in sake yeast including descriptions of the genes known to contribute to SAM and folate accumulation and the underlying mechanisms.
