Phenotypes of a mutant
quicker progressing through the [wiki|sporulation ] cycle [Pubmed|22463703]
overexpression of CmpA results in heat-sensitive sporulation [Pubmed|22463703,26387458], this can be suppressed by mutations in ''[gene|CB06A70DE7462CEB7AF5D8C28943C878DD56DE1A|clpP]'' and ''[gene|297F53DAD3351E0C55108DD2C93B78FFB174438C|clpX]'' [Pubmed|26387458]
