Structure of ManS and ManR.

(A) Scheme of ManS and alignment of the putative periplasmic domains of ManS and homologous proteins from other cyanobacteria. Boldface letters indicate conserved amino acids. 6803, Synechocystis sp PCC 6803; 7120, Anabaena sp PCC 7120; Nost, Nostoc punctiforme.

(B) Alignment of the putative periplasmic domains of ManS and CPx-type ATPase of Halobacterium. Conserved amino acids are shown on the bottom line. Plus signs indicate the conservation of similar amino acids.

(C) Scheme of ManR and alignment of the putative DNA binding domains of homologous proteins. Boldface letters indicate conserved amino acids.
