FunctionTENA_BACSU Stimulates the production of several extracellular degradative enzymes at the transcriptional level, probably by interfering with DegS and DegU, which are required for this effect. Is not an essential protein, but affects the sporulation frequency. Evolutionary Conservation Check, as determined by ConSurfDB.
