Pathwayi: L-isoleucine biosynthesis

This protein is involved in step 4 of the subpathway that synthesizes L-isoleucine from 2-oxobutanoate.UniRule annotation
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Acetolactate synthase (ilvB)
  2. Ketol-acid reductoisomerase (NADP(+)) (ilvC)
  3. Dihydroxy-acid dehydratase (ilvD), Dihydroxy-acid dehydratase (ilvD)
  4. Branched-chain-amino-acid aminotransferase (ilvE)
This subpathway is part of the pathway L-isoleucine biosynthesis, which is itself part of Amino-acid biosynthesis.
