    Summary
    Enables N-acetylmuramoyl-L-alanine amidase activity. Involved in defense response to Gram-positive bacterium; negative regulation of defense response to bacterium; and peptidoglycan catabolic process. Located in extracellular region. Is expressed in several structures, including adult fat body; adult head; adult oenocyte; embryonic/larval gut; and embryonic/larval proventriculus.
