Expression of lacZ transcriptional fusions in P. denitrificans. The effects of prrA and ppsR on the bchF-lacZ, crtA-lacZ, and pucB1-lacZ transcriptional fusions were determined. Black bars, vector pRK415; light gray bars, pSmNs (pRK415:ppsR); dark gray bars, pSmNsABC (pRK415:ppsR:prrBAC). One unit of β-galactosidase activity equals 1 nmol ONPG A600 unit−1 ml culture−1 min−1. Average data from three independent experiments are shown, with standard deviations not exceeding 15% of the averages.
