Involvement of a CbbR homolog in low CO2-induced activation of the bicarbonate transporter operon in cyanobacteria.

Journal of bacteriology - 1 Mar 2001

Abstract excerpt

The cmpABCD operon of Synechococcus sp. strain PCC 7942, encoding a high-affinity bicarbonate transporter, is transcribed only under CO2-limited conditions. In Synechocystis sp. strain PCC 6803, the slr0040, slr0041, slr0043, and slr0044 genes, forming an operon with a putative porin gene (slr0042), were identified as the cmpA, cmpB, cmpC, and cmpD genes, respectively, on the basis of their strong similarities to...
