Identification, cloning, and expression of the Escherichia coli pyrazinamidase and nicotinamidase gene, pncA [PDF]
Antimicrobial Agents and Chemotherapy, 1996 Pyrazinamide (PZA) is one of the three most important drugs for treatment of Mycobacterium tuberculosis infections. The antibacterial activity of PZA requires a bacterial enzyme, pyrazinamidase (PZAase), which hydrolyzes PZA to form pyrazinoic acid and ammonia. Most PZA-resistant clinical M. tuberculosis isolates lack PZAase activity.

Colorimetric methods for rapid determination of pyrazinamide resistance
International Journal of Mycobacteriology, 2020 Background: Because pyrazinamide (PZA) is only effective for Mycobacterium tuberculosis at an acidic pH, susceptibility tests are more difficult to perform than those for other anti-tuberculosis (TB) drugs.

Mycobacterium smegmatis Has Two Pyrazinamidase Enzymes, PncA and PzaA [PDF]
Journal of Bacteriology, 2000 ABSTRACT The Mycobacterium smegmatis pncA gene, encoding nicotinamidase/pyrazinamidase, was identified. While it was similar to counterparts from other mycobacteria, the M. smegmatis PncA had little homology to the other M.

Brucella abortus nicotinamidase (PncA) contributes to its intracellular replication and infectivity in mice [PDF]
FEMS Microbiology Letters, 2004 Brucella spp. are facultative intracellular pathogens that have the ability to survive and multiply in professional and non-professional phagocytes, and cause abortion in domestic animals and undulant fever in humans. The mechanism and factors of virulence are not fully understood.
