DE RecName: Full=Dihydrofolate reductase; DE Short=DHFR; DE EC=1.5.1.3; GN Name=folA; OrderedLocusNames=SAR1439; OS Staphylococcus aureus (strain MRSA252). OC Bacteria; Firmicutes; Bacillales; Staphylococcus. OX NCBI_TaxID=282458; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RX PubMed=15213324; DOI=10.1073/pnas.0402521101; RA Holden M.T.G., Feil E.J., Lindsay J.A., Peacock S.J., Day N.P.J., RA Enright M.C., Foster T.J., Moore C.E., Hurst L., Atkin R., Barron A., RA Bason N., Bentley S.D., Chillingworth C., Chillingworth T., RA Churcher C., Clark L., Corton C., Cronin A., Doggett J., Dowd L., RA Feltwell T., Hance Z., Harris B., Hauser H., Holroyd S., Jagels K., RA James K.D., Lennard N., Line A., Mayes R., Moule S., Mungall K., RA Ormond D., Quail M.A., Rabbinowitsch E., Rutherford K.M., Sanders M., RA Sharp S., Simmonds M., Stevens K., Whitehead S., Barrell B.G., RA Spratt B.G., Parkhill J.; RT "Complete genomes of two clinical Staphylococcus aureus strains: RT evidence for the rapid evolution of virulence and drug resistance."; RL Proc. Natl. Acad. Sci. U.S.A. 101:9786-9791(2004). CC -!- CATALYTIC ACTIVITY: 5,6,7,8-tetrahydrofolate + NADP(+) = 7,8- CC dihydrofolate + NADPH. CC -!- PATHWAY: Cofactor biosynthesis; tetrahydrofolate biosynthesis; CC tetrahydrofolate from dihydrofolate: step 1/1. CC -!- MISCELLANEOUS: The reaction catalyzed by this enzyme represents an CC essential step for de novo glycine and purine synthesis, DNA CC precursor synthesis, and for the conversion of dUMP to dTMP. CC -!- SIMILARITY: Belongs to the dihydrofolate reductase family. CC -!- SIMILARITY: Contains 1 DHFR (dihydrofolate reductase) domain.
