Protein
Probable methylenetetrahydrofolate reductase
Gene
Os03g0815200, LOC_Os03g60090, OSJNBa0024F18.2, OSJNBb0042K11.1
Organism
Oryza sativa subsp. japonica (Rice)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

The probable reversibility of the MTHFR reaction in plants suggests that they can metabolize the methyl group of 5,10-methylenetetrahydrofolate to serine, sugars and starch By similarity.

Catalytic activityi

5-methyltetrahydrofolate + NAD(P)+ = 5,10-methylenetetrahydrofolate + NAD(P)H.

Cofactori

FAD By similarity.

Enzyme regulationi

Plant MTHFRs strongly prefer NADH over NADPH. Not inhibited by methionine or S-adenosylmethionine By similarity.
