General annotation (Comments)

Function

Catalyzes the reversible reaction in which hydroxymethyl group from 5,10-methylenetetrahydrofolate is tranferred onto alpha-ketoisovalerate to form ketopantoate By similarity. HAMAP MF_00156

Catalytic activity

5,10-methylenetetrahydrofolate + 3-methyl-2-oxobutanoate + H2O = tetrahydrofolate + 2-dehydropantoate. HAMAP MF_00156

Cofactor

Binds 1 magnesium ion per subunit By similarity. HAMAP MF_00156

Pathway

Cofactor biosynthesis; (R)-pantothenate biosynthesis; (R)-pantoate from 3-methyl-2-oxobutanoate: step 1/2. HAMAP MF_00156

Subunit structure

Homodecamer; pentamer of dimers By similarity. HAMAP MF_00156

Subcellular location

Cytoplasm Potential HAMAP MF_00156.

Sequence similarities
