Functional organization of the glnB-glnA cluster of Azospirillum brasilense.

Journal of bacteriology - 1 May 1993

de Zamaroczy M, Paquelin A, Elmerich C

Abstract excerpt

The functional organization of the glnB-A cluster of Azospirillum brasilense, which codes for the PII protein and glutamine synthetase, respectively, was studied with the aid of lacZ fusions, deletion mapping, site-directed mutagenesis, and complementation. It was shown previously by mRNA mapping that the cluster contains two tandemly organized promoters, glnBp1 and glnBp2, of the sigma 70 and sigma 54 types,...
