FIG 4.

CotG versions. The wild-type protein (CotG) is represented as being composed of three domains: the N- and C-terminal regions of 34 and 35 amino acids, respectively, and a central domain of 126 amino acids organized into tandem repeats (18). CotGΔ lacks the central domain, and CotG-Cterm and CotG-Nterm contain only the C- and N-terminal domains, respectively. All constructs were integrated into the chromosomes of strains carrying either a null mutation in cotG or a double-null mutation in cotG and cotH (indicated in parentheses). The names of strains carrying the different cotG alleles in the two genetic backgrounds are shown.
