The contribution of SpoVDCd domains to sporulation. A. The domain organisation of SpoVDCd showing Pfam predictions [33]. B. Sporulation efficiency of R20291, R20291ΔspoVD and R20291ΔspoVD complemented in trans using plasmids expressing a series of mutant CLIP-SpoVDs under the control of a constitutive promoter: full-length CLIP-SpoVDCd (spoVD); CLIP-SpoVDCd lacking the PBP dimerization domain (ΔDimerization), PASTA domain (ΔPASTA), transpeptidase domain (ΔTranspeptidase) or both PBP dimerization and PASTA domains (ΔDimer & PASTA); CLIP-SpoVDCd lacking the active site nucleophile serine (S311A). Shown is the sporulation efficiency after 5 days in broth culture, expressed as number of spores as a percentage of total viable CFUs. Experiments were conducted in duplicate on biological triplicates and mean and standard deviations are shown.
