    Pathwayi: 4-chlorobenzoate degradation

    This protein is involved in step 3 of the subpathway that synthesizes 4-hydroxybenzoate from 4-chlorobenzoate.
    Proteins known to be involved in the 3 steps of the subpathway in this organism are:
    1. no protein annotated in this organism
    2. 4-chlorobenzoyl coenzyme A dehalogenase-2 (fcbB2), 4-chlorobenzoyl coenzyme A dehalogenase-1 (fcbB1), 4-chlorobenzoate--CoA ligase (fcbA1), 4-chlorobenzoate--CoA ligase (fcbA2)
    3. 4-hydroxybenzoyl-CoA thioesterase (fcbC)
    This subpathway is part of the pathway 4-chlorobenzoate 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 4-hydroxybenzoate from 4-chlorobenzoate, the pathway 4-chlorobenzoate degradation and in Xenobiotic 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.
