This domain is found N-terminal in Carboxy-terminal processing protease CtpB and related proteins. This enzyme is involved in signal transduction pathway leading to the proteolytic activation of the mother cell transcription factor pro-sigma-K during sporulation. This domain contains auto-cleavage site at which it is proteolytically cleaved. The remaining part in the mature enzyme is involved in dimerisation [1].	Domain

This domain is composed of three alpha helices [1]. This domain is found at the N or C terminus of a variety of enzymes involved in bacterial cell wall degradation [2]. This domain may have a general peptidoglycan binding function. This family is found N-terminal to the catalytic domain of matrixins [3]. The domain is found to bind peptidoglycan experimentally [4].
