Autolysin
Definition
An enzymatic substance (hydrolase) produced by a bacterial or animal cell, capable of dissolving or decomposing the membrane, cell wall, or internal biological structures of the organism that secreted it. In microbiology, these specific enzymes control cell division, peptidoglycan wall remodeling, and spontaneous bacterial lysis during the decline phase of a cellular culture.
