Protein
5-formyltetrahydrofolate cyclo-ligase
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Only enzyme known to utilize 5-formyltetrahydrofolate (folinic acid) as substrate. Contributes to tetrahydrofolate metabolism in an alternative way of folate biosynthesis. May regulate carbon flow through the folate-dependent one-carbon metabolic network that supplies carbon for the biosynthesis of purines, thymidine and amino acids.
Similarity
Belongs to the 5-formyltetrahydrofolate cyclo-ligase family.
