Metabolite Identification
Common NameN-Acetylmuramate
DescriptionN-Acetylmuramate, also known as acetylmuramic acid or 4-O-nacmur, belongs to the class of organic compounds known as acylaminosugars. These are organic compounds containing a sugar linked to a chain through N-acyl group. These are carbohydrate derivatives containing a hexose moeity in which the oxygen atom is replaced by an n-acyl group. N-Acetylmuramate is a moderately basic compound (based on its pKa). N-Acetylmuramate exists in all living organisms, ranging from bacteria to humans.

Enzymes

General function:
Involved in N-acetylmuramoyl-L-alanine amidase activity
Specific function:
Pattern receptor that binds to murein peptidoglycans (PGN) of Gram-positive bacteria. Has bactericidal activity towards Gram-positive bacteria. May kill Gram-positive bacteria by interfering with peptidoglycan biosynthesis. Binds also to Gram-negative bacteria, and has bacteriostatic activity towards Gram-negative bacteria. Plays a role in innate immunity.
