Regulation of nitrogen fixation in Azospirillum brasilense Sp7: involvement of nifA, glnA and glnB gene products.

Y Y Liang1, M de Zamaroczy, F Arsène, A Paquelin, C Elmerich.   

Abstract

The expression of nifA-, niH- and nifB-lacZ fusions was examined in different mutants of Azospirillum brasilense. Mutations in nifA, glnA and glnB severely impaired the expression of nifH- and nifB-lacZ fusions. By contrast, a nifA-lacZ fusion was not affected in a nifA or a glnB background and was only partially impaired in glnA mutants. It is proposed that in A. brasilense, the PII protein and glutamine synthetase are involved in a post-translational modification of NifA.
