Activation of the Anabaena nir operon promoter requires both NtcA (CAP family) and NtcB (LysR family) transcription factors.

Molecular microbiology - 1 Nov 2000

Frías J E, Flores E, Herrero A

Abstract excerpt

A region of the genome of the heterocyst-forming cyanobacterium Anabaena sp. PCC 7120 containing the ntcB gene was identified. This region is located upstream from the nir operon involved in nitrate assimilation in this cyanobacterium. An Anabaena ntcB mutant was able to use ammonium and dinitrogen as sources of nitrogen for growth but was unable to assimilate nitrate. Enzymes of the nitrate reduction system were...
