Mutational analysis of the phosphate-binding loop of Rhizobium meliloti DctD, a sigma54-dependent activator.

Journal of bacteriology - 1 May 1998

Gao Y, Wang Y K, Hoover T R

Abstract excerpt

The phosphate-binding loop of sigma54-dependent activators is thought to participate in ATP binding and/or hydrolysis. Alanine substitutions at positions 3, 4, 6, 7, and 8 of this motif in Rhizobium meliloti DctD disrupted transcriptional activation and ATP hydrolysis. Interestingly, substitution...
