Protein

2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoate hydrolase

Gene

bphD

Organism
Pseudomonas putida (Arthrobacter siderocapsulatus)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes an unusual C-C bond hydrolysis of 2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoic acid (HOPDA) to produce benzoic acid and 2-hydroxy-2,4-pentadienoic acid (HPD).1 Publication

Catalytic activityi

2,6-dioxo-6-phenylhexa-3-enoate + H2O = benzoate + 2-oxopent-4-enoate.

Pathwayi: biphenyl degradation

This protein is involved in step 4 of the subpathway that synthesizes 2-hydroxy-2,4-pentadienoate and benzoate from biphenyl.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Cis-2,3-dihydrobiphenyl-2,3-diol dehydrogenase (bphB)
  3. no protein annotated in this organism
  4. 2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoate hydrolase (bphD)
This subpathway is part of the pathway biphenyl degradation, which is itself part of Xenobiotic degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 2-hydroxy-2,4-pentadienoate and benzoate from biphenyl, the pathway biphenyl degradation and in Xenobiotic 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.
