SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
Description5,10-Methylene-THF, also known as CH2H4folate, belongs to the class of organic compounds known as tetrahydrofolic acids. These are heterocyclic compounds based on the 5,6,7,8-tetrahydropteroic acid skeleton conjugated with at least one L-glutamic acid unit. 5,10-Methylene-THF is a strong basic compound (based on its pKa). 5,10-Methylene-THF exists in all eukaryotes, ranging from yeast to humans. Within yeast, 5,10-methylene-THF participates in a number of enzymatic reactions. In particular, glycine and 5,10-methylene-THF can be biosynthesized from L-serine and tetrahydrofolic acid through the action of the enzyme serine hydroxymethyltransferase, mitochondrial. In addition, glycine and 5,10-methylene-THF can be biosynthesized from L-serine and tetrahydrofolic acid through the action of the enzyme serine hydroxymethyltransferase. In yeast, 5,10-methylene-THF is involved in the metabolic pathway called the serine metabolism pathway.
