Protein

Alpha-aminoadipic semialdehyde synthase, mitochondrial

Gene

Aass

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Bifunctional enzyme that catalyzes the first two steps in lysine degradation. The N-terminal and the C-terminal contain lysine-oxoglutarate reductase and saccharopine dehydrogenase activity, respectively (By similarity).By similarity

Catalytic activityi

N(6)-(L-1,3-dicarboxypropyl)-L-lysine + NADP+ + H2O = L-lysine + 2-oxoglutarate + NADPH.By similarity
N(6)-(L-1,3-dicarboxypropyl)-L-lysine + NAD+ + H2O = L-glutamate + (S)-2-amino-6-oxohexanoate + NADH.

Pathwayi: L-lysine degradation via saccharopine pathway

This protein is involved in step 1 and 2 of the subpathway that synthesizes glutaryl-CoA from L-lysine.
Proteins known to be involved in the 6 steps of the subpathway in this organism are:
  1. Alpha-aminoadipic semialdehyde synthase, mitochondrial (Aass)
  2. Alpha-aminoadipic semialdehyde synthase, mitochondrial (Aass)
  3. no protein annotated in this organism
  4. Kynurenine/alpha-aminoadipate aminotransferase, mitochondrial (Aadat)
  5. no protein annotated in this organism
  6. Dihydrolipoyllysine-residue succinyltransferase component of 2-oxoglutarate dehydrogenase complex, mitochondrial (Dlst)
This subpathway is part of the pathway L-lysine degradation via saccharopine 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 glutaryl-CoA from L-lysine, the pathway L-lysine degradation via saccharopine pathway and in Amino-acid degradation.

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.
