Physiological role of the GlnK signal transduction protein of Escherichia coli: survival of nitrogen starvation.

Molecular microbiology - 1 Oct 2002

Blauwkamp Timothy A, Ninfa Alexander J

Abstract excerpt

Escherichia coli contains two PII-like signal trans-duction proteins, PII and GlnK, involved in nitrogen assimilation. We examined the roles of PII and GlnK in controlling expression of glnALG, glnK and nac during the transition from growth on ammonia to nitrogen starvation and vice versa. The PII protein exclusively controlled glnALG expression in cells adapted to growth on ammonia, but was unable to limit nac...
