	Abstract

A DNA damaging agent, the mitomycin C, derepresses the site-specific excision of two integrative and potentially conjugative elements from Streptococcus thermophilus, ICESt1 and ICESt3. This regulation pathway involves a repressor related to phage lambda cI repressor. It could also involve a putative regulator related to another type of phage repressors, the "cI-like" repressors.
