Glycosyl hydrolase 108. This family acts as a lysozyme (N-acetylmuramidase), EC:3.2.1.17. It contains a conserved EGGY motif near the N-terminus, the glutamic acid within this motif is essential for catalytic activity. In bacteria, it may activate the secretion of large proteins via the breaking and rearrangement of the peptidoglycan layer during secretion. It is frequently found at the N-terminus of proteins containing a C-terminal pfam09374 domain.
