P-hydroxybenzoic acid hydrazide

Chorismate lyase is an enzyme that transforms chorismate into 4-hydroxybenzoate and pyruvate. This enzyme catalyses the first step in ubiquinone biosynthesis in Escherichia coli and other Gram-negative bacteria. Benzoate 4-monooxygenase is an enzyme that utilizes benzoate, NADPH, H and O2 to produce 4-hydroxybenzoate, NADP and H2O. This enzyme can be found in Aspergillus niger.
