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].

A, B	PF01510	N-acetylmuramoyl-L-alanine amidase (Amidase_2)	N-acetylmuramoyl-L-alanine amidase	This family includes zinc amidases that have N-acetylmuramoyl-L-alanine amidase activity EC:3.5.1.28. This enzyme domain cleaves the amide bond between N-acetylmuramoyl and L-amino acids in bacterial cell walls (preferentially: D-lactyl-L-Ala). The ...	This family includes zinc amidases that have N-acetylmuramoyl-L-alanine amidase activity EC:3.5.1.28. This enzyme domain cleaves the amide bond between N-acetylmuramoyl and L-amino acids in bacterial cell walls (preferentially: D-lactyl-L-Ala). The structure is known for the bacteriophage T7 structure and shows that two of the conserved histidines are zinc binding.	Domain
