Additional information
not fully active in laboratory strains due to a mutation (V117A) [pubmed|27501195]
the poor interaction of [protein|DC3449D5F195E5C2E9E14FEC95396C8F1FDF73B4|sigH] with the [wiki|RNA polymerase] is responsible for the poor [wiki|sporulation] at high salinity, this phenotype can be partially suppressed by specific mutations in [protein|DC3449D5F195E5C2E9E14FEC95396C8F1FDF73B4|sigH] [Pubmed|26712348]
