== Function ==
[[http://www.uniprot.org/uniprot/DYR_CHICK DYR_CHICK]] Key enzyme in folate metabolism. Contributes to the de novo mitochondrial thymidylate biosynthesis pathway. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis. May bind to mRNA.
