RC STRAIN=MGAS5005 / Serotype M1; RX PubMed=16088826; DOI=10.1086/432514; RA Sumby P., Porcella S.F., Madrigal A.G., Barbian K.D., Virtaneva K., RA Ricklefs S.M., Sturdevant D.E., Graham M.R., Vuopio-Varkila J., RA Hoe N.P., Musser J.M.; RT "Evolutionary origin and emergence of a highly successful clone of RT serotype M1 group A Streptococcus involved multiple horizontal gene RT transfer events."; RL J. Infect. Dis. 192:771-782(2005). CC -!- FUNCTION: Catalyzes the NADPH-dependent reduction of ketopantoate CC into pantoic acid (By similarity). CC -!- CATALYTIC ACTIVITY: (R)-pantoate + NADP(+) = 2-dehydropantoate + CC NADPH. CC -!- PATHWAY: Cofactor biosynthesis; pantothenate biosynthesis; CC pantoate from 3-methyl-2-oxobutanoate: step 2. CC -!- SUBCELLULAR LOCATION: Cytoplasm (Potential). CC -!- SIMILARITY: Belongs to the ketopantoate reductase family.
