Abstract
We isolated an rpoD2 gene encoding the potential sigma factor of RNA p olymerase from the cyanobacterium Microcystis aeruginosa K-81, which c an perform photosynthesis. The deduced amino acid sequence of RpoDZ (s igma(A2)) exhibits extensive homology to other eubacterial RpoD protei ns. This gene possessed multiple 5'-end transcripts, expressed specifi cally under light (P-L), dark (P-D), or constitutively light/dark (P-C ) conditions during exponential cell growth.
