Phenotypes of a mutant
essential [Pubmed|12682299]
terminal phenotype of a CRISPRi knockdown mutant is moderate bulging [Pubmed|27238023]
the mutant is viable and Fe-S clusters are dispensable if [protein|search|IspG ]and [protein|search|IspH ]from the MEP pathway for isoprenoid biosynthesis are bypassed by a heterologous mevalonate pathway which allows B. subtilis to synthesize isopentenyl diphosphate and diphosphomevalonate [pubmed|29292548]
