Mutation in ntrC gene leading to the derepression of nitrogenase synthesis in Rhodobacter sphaeroides.

FEMS microbiology letters - 1 Feb 1997

Zinchenko V, Babykin M, Glaser V, Mekhedov S, Shestakov S

Abstract excerpt

The Rhodobacter sphaeroides mutants Drn12 and Drn21 derepressed for nitrogenase synthesis in the presence of ammonia and impaired in utilization of certain nitrogen sources have been analyzed. Both mutants show a low level of expression of the glnBA operon. The DNA fragment restoring the wild-type phenotype to these mutants contains the 3'-portion of ntrB gene and the entire ntrC gene. Sequence analysis showed...
