Homogentisate 1,2-dioxygenase

Gene

hmgA

Organism
Ralstonia pickettii (strain 12J)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Involved in the catabolism of homogentisate (2,5-dihydroxyphenylacetate or 2,5-OH-PhAc), a central intermediate in the degradation of phenylalanine and tyrosine. Catalyzes the oxidative ring cleavage of the aromatic ring of homogentisate to yield maleylacetoacetate.UniRule annotation

Catalytic activityi

Homogentisate + O2 = 4-maleylacetoacetate.UniRule annotation

Cofactori

Fe cationUniRule annotation

Pathwayi: L-phenylalanine degradation

This protein is involved in step 4 of the subpathway that synthesizes acetoacetate and fumarate from L-phenylalanine.UniRule annotation
Proteins known to be involved in the 6 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. no protein annotated in this organism
  3. no protein annotated in this organism
  4. Homogentisate 1,2-dioxygenase (hmgA)
  5. no protein annotated in this organism
  6. no protein annotated in this organism
This subpathway is part of the pathway L-phenylalanine degradation, which is itself part of 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.
