3-carboxy-cis,cis-muconate cycloisomerase (IPR012789)

Short name: Protocat_PcaB

Overlapping homologous superfamilies

Family relationships


Proteins in this entry are 3-carboxy-cis,cis-muconate cycloisomerases, which catalyse the second step in the protocatechuate degradation to beta-ketoadipate and then to succinyl-CoA and acetyl-CoA. 4-hydroxybenzoate, 3-hydroxybenzoate, and vanillate can all be converted in one step to protocatechuate. All members of the seed alignment for this entry were chosen from within protocatechuate degradation operons of at least three genes of the pathway, and from genomes with the complete pathway through beta-ketoadipate.
