Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Autolysins are involved in some important biological processes such as cell separation, cell-wall turnover, competence for genetic transformation, formation of the flagella and sporulation. Autolysin strictly depends on the presence of choline-containing cell walls for activity.
Catalytic activity	Hydrolyzes the link between N-acetylmuramoyl residues and L-amino acid residues in certain cell-wall glycopeptides.
Subcellular location	SecretedPotential.
Domain	The C-terminal domain could be responsible for the substrate recognition.
Sequence similarities	Belongs to the N-acetylmuramoyl-L-alanine amidase 2 family. Contains 6 cell wall-binding repeats.
