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