Abstract
The production of streptocins STH 1 and STH 2 by Streptococcus gordonii DL1 (Challis) is directly controlled by the competence regulon, which requires intact comR and comAB loci. The streptocin ( sth ) locus comprises two functional genes, sthA and sthB . Whereas STH 1 activity requires sthA alone, STH 2 activity depends on both genes.Keywords
