[1]	NUCLEOTIDE SEQUENCE [GENOMIC DNA]. STRAIN=J120; PubMed=1941991 [NCBI, ExPASy, EBI, Israel, Japan] Wylie B.A., Koornhof H.J.; "Nucleotide sequence of dihydrofolate reductase type VI."; J. Med. Microbiol. 35:214-218(1991).

Comments

CATALYTIC ACTIVITY: 5,6,7,8-tetrahydrofolate + NADP⁺ = 7,8-dihydrofolate + NADPH.
PATHWAY: Cofactor biosynthesis; tetrahydrofolate biosynthesis; tetrahydrofolate from dihydrofolate: step 1/1 .
SUBUNIT: Homodimer (By similarity).
MISCELLANEOUS: The reaction catalyzed by this enzyme represents an essential step for de novo glycine and purine synthesis, DNA precursor synthesis, and for the conversion of dUMP to dTMP.
SIMILARITY: Belongs to the dihydrofolate reductase family.
SIMILARITY: Contains 1 DHFR (dihydrofolate reductase) domain.
