4.1.3.B3 | evolution | the protocatechuate 4,5-cleavage pathway is mainly distributed in alpha- and beta-proteobacteria, gene clusters of protocatechuate 4,5-cleavage pathway in strain CNB-1 and other bacterial strains, genotyping and phylogenetic analysis, overview. Two types of genetic organization/cluster are recognized for PCA 4,5-cleavage pathway: The Sphingobium-type gene cluster constitutes several transcriptional units. The Comamonas-Pseudomonas type constitutes only one transcriptional unit | Comamonas testosteroni |
4.1.3.B3 | metabolism | the enzyme catalyzes the last step of the protocatechuate 4,5-cleavage pathway. Vanillate, 3-hydroxybenzoate, and 4-hydroxybenzoate are degraded via protocatechuate 4,5-cleavage pathway | Comamonas testosteroni |

4.2.1.83 | malfunction | a pmdE knock out mutant loses the ability to grow on vanillate, 3-hydroxybenzoate, and 4-hydroxybenzoate as carbon sources. This ability to grow on vanillate, 3-hydroxybenzoate, and 4-hydroxybenzoate is restored by genetic complementation | Comamonas testosteroni |
4.2.1.83 | metabolism | the enzyme is active in the protocatechuate 4,5-cleavage pathway. Gene pmdU encodes an 4-oxalomesaconate tautomerase and catalyzes conversion of 4-oxalomesaconate-keto into 4-oxalomesaconate-enol, which is the only substrate of 4-oxalomesaconate hydratase. Pathway overview | Comamonas testosteroni |
4.2.1.83 | physiological function | the enzyme in strain CNB-1 is essential for growth on phenol, gentisate, vanillate, 3-hydroxybenzoate, and 4-hydroxybenzoate as carbon and energy sources | Comamonas testosteroni |
