[Construction of an alr3504 defected mutant and its phenotype analysis in anabaena PCC7120].

Abstract excerpt

C-di-GMP [Bis-(3',5')-cyclic dimeric guanosine monophosphate] is a novel global second messenger in bacteria. The diguanylate cyclase and phosphodiesterase involve in c-di-GMP synthesis and degradation, respectively. alr3504 in Anabaena PCC7120 possibly encodes diguanylate cyclase with a coserved GGDEF domain. [Objective] For functional characterization, [Methods] the deletion mutant of alr3504 was constructed by...
