Mycobacterium smegmatis has two pyrazinamidase enzymes, PncA and pzaA.
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. smegmatis pyrazinamidase/nicotinamidase, encoded by the pzaA gene. Transformation of Mycobacterium bovis strain BCG with M. smegmatis pncA or pzaA conferred susceptibility to pyrazinamide.
