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].	Domain
A	PF01464	Transglycosylase SLT domain (SLT)	Transglycosylase SLT domain	This family is distantly related to Pfam:PF00062. Members are found in phages, type II, type III and type IV secretion systems (reviewed in [4]).	Domain
