(2R)-2,3-dihydroxy-3-methylbutanoate + NADP+ = (2S)-2-hydroxy-2-methyl-3-oxobutanoate + NADPH.
(2R,3R)-2,3-dihydroxy-3-methylpentanoate + NADP+ = (S)-2-hydroxy-2-ethyl-3-oxobutanoate + NADPH.

Pathwayi: L-isoleucine biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes L-isoleucine from 2-oxobutanoate.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Acetolactate synthase large subunit (ilvB)
  2. Ketol-acid reductoisomerase (ilvC)
  3. Dihydroxy-acid dehydratase (ilvD)
  4. no protein annotated in this organism
This subpathway is part of the pathway L-isoleucine biosynthesis, which is itself part of Amino-acid biosynthesis.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
