Pathway: L-leucine biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes L-leucine from 3-methyl-2-oxobutanoate.UniRule annotation
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. 2-isopropylmalate synthase (leuA)
  2. 3-isopropylmalate dehydratase small subunit (leuD), 3-isopropylmalate dehydratase large subunit (leuC)
  3. 3-isopropylmalate dehydrogenase (leuB)
  4. Branched-chain-amino-acid aminotransferase (ilvE)
This subpathway is part of the pathway L-leucine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-leucine from 3-methyl-2-oxobutanoate, the pathway L-leucine biosynthesis and in Amino-acid biosynthesis.

Similar proteinsi

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 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.
