<p>This family of bacterial proteins are variously described as 'hypothetical protein yifB', 'competence protein', 'hypothetical protein' or 'Mg chelatase-related protein'. These proteins are a subset of the magnesium chelatase, ChlI subunit family and either belong to or show significant homology to the non-peptidase homologs of the MEROPS peptidase family S16 (lon protease family, clan SF), <db_xref db="INTERPRO" dbkey="IPR001984"/>. </p> Mg chelatase-related protein
