Functioni

Catalytic activityi

L-threonine + NAD+ = L-2-amino-3-oxobutanoate + NADH.By similarity

Pathwayi: L-threonine degradation via oxydo-reductase pathway

This protein is involved in step 1 of the subpathway that synthesizes glycine from L-threonine.Curated
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. L-threonine 3-dehydrogenase, mitochondrial (Tdh)
  2. 2-amino-3-ketobutyrate coenzyme A ligase, mitochondrial (Gcat)
This subpathway is part of the pathway L-threonine degradation via oxydo-reductase pathway, which is itself part of Amino-acid degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes glycine from L-threonine, the pathway L-threonine degradation via oxydo-reductase pathway and in Amino-acid degradation.

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 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.
