NtcA, a global nitrogen regulator from the cyanobacterium Synechococcus that belongs to the Crp family of bacterial regulators.

Molecular microbiology - 1 Jul 1992

Vega-Palas M A, Flores E, Herrero A

Abstract excerpt

The gene ntcA is required for full expression of proteins subject to ammonium repression in the cyanobacterium Synechococcus. A 3.1 kb DNA fragment able to complement an ntcA mutant was digested with exonuclease III, and deleted fragments of different size were tested for complementation of that mutant, allowing the localization of its mutation within a BamHI-HindIII genomic fragment of c. 0.4 kb. Insertion of a...
