Pathwayi: L-isoleucine biosynthesis

This protein is involved in step 3 of the subpathway that synthesizes L-isoleucine from 2-oxobutanoate.UniRule annotation1 Publication
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Acetolactate synthase isozyme 1 small subunit (ilvN), Acetolactate synthase isozyme 1 large subunit (ilvB), Acetolactate synthase isozyme 2 small subunit (ilvM), Acetolactate synthase isozyme 3 large subunit (ilvI), Acetolactate synthase isozyme 3 small subunit (ilvH), Acetolactate synthase isozyme 2 large subunit (ilvG)
  2. Ketol-acid reductoisomerase (NADP(+)) (ilvC)
  3. 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.

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.
