FIG. 1.

Protein sequence alignment of SpoIVB peptidase domains. Sequences were aligned using ClustalW (32) and the figure was generated using ALSCRIPT (2). Abbreviations: Bsub, B. subtilis (accession no. P17896, residues 187 to 425); Bhal, B. halodurans (Q9K975, 197 to 437); Cdif, C. difficile (Q46028, 124 to 352); Bant, B. anthracis (www.tigr.org/tdb/mdb/mdbinprogress.html); Chyd, C. hydrogenoformans (www.tigr.org/tdb/mdb/mdbinprogress.html); Bste, B. stearothermophilus (www.genome.ou/bstearo.html); Cace, C. acetobutylicum (www.genomecorp.com/genesequences/clostridium/clospage.html). Sequences without accession numbers were derived from the unfinished genome DNA sequences. Strictly conserved amino acids are boxed, positions of the SpoIVB mutants described are labeled and numbered, and the putative catalytic triad residues are highlighted with an asterisk.
