Protein

Methylenetetrahydrofolate reductase 2

Gene

MTHFR2

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein 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.1 Publication

Catalytic activityi

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

Cofactori

FADBy similarity

Enzyme regulationi

Plant MTHFRs strongly prefer NADH over NADPH. Not inhibited by methionine or S-adenosylmethionine.1 Publication
