muramidase

Description

Muramidase: A basic enzyme that is present in saliva, tears, egg white, and many animal fluids. It functions as an antibacterial agent. The enzyme catalyzes the hydrolysis of 1,4-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrin. EC 3.2.1.17. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

Research Excerpts

Overview

Muramidase is an enzyme that hydrolyzes peptidoglycans of bacterial cell walls. It is a marker of mononuclear phagocytic cells. We have investigated the synovial membrane for the presence of this enzyme in cells.
