[1]	NUCLEOTIDE SEQUENCE [GENOMIC DNA]. Wernegreen J.J., Moran N.A.; "Accelerated evolutionary rates at biosynthetic loci of Buchnera-Uroleucon."; Submitted (DEC-1999) to the EMBL/GenBank/DDBJ databases.

Comments

CATALYTIC ACTIVITY: (R)-2,3-dihydroxy-3-methylbutanoate + NADP⁺ = (S)-2-hydroxy-2-methyl-3-oxobutanoate + NADPH.
CATALYTIC ACTIVITY: (2R,3R)-2,3-dihydroxy-3-methylpentanoate + NADP⁺ = (S)-2-hydroxy-2-ethyl-3-oxobutanoate + NADPH.
PATHWAY: Amino-acid biosynthesis; L-isoleucine biosynthesis; L-isoleucine from 2-oxobutanoate: step 2/4 .
PATHWAY: Amino-acid biosynthesis; L-valine biosynthesis; L-valine from pyruvate: step 2/4 .
SIMILARITY: Belongs to the ketol-acid reductoisomerase family.
