Accumulation of mutant SpoVE proteins during sporulation. (A) Strains were induced to sporulate in DSM medium and collected 6 h after the onset of sporulation for Western blot analysis using an anti-gfp antibody. wt (wild type), spoVE85 amyE::spoVE-yfp (AH3561); C160R, spoVE85 amyE::spoVE(C160R)-yfp (AH3704); C82R, spoVE85 amyE::spoVE(C82R)-yfp (AH3701); S103N, spoVE85 amyE::spoVE(S103N)-yfp (AH3702); E126G, spoVE85 amyE::spoVE(E126G)-yfp (AH3703); I58N, spoVE85 amyE::spoVE(I59N)-yfp (AH3700); G292R, spoVE85 amyE::spoVE(G292R)-yfp (AH3705); G355D, spoVE85 amyE::spoVE(G355D)-yfp (AH3706); no YFP, wild-type spoVE (MB24).
