Has weak antibacterial activity, mainly against marine Gram-positive bacteria like C.maltaromaticum (MIC=200 uM), C.mobile (MIC=100 uM), C.divergens (MIC=200 uM) and C.funditum (MIC=200 uM) but also against C.glutamicum (MIC=50 uM). Has very little or no activity against Gram-negative bacteria. The amidated form is probably the active form. Amidated. Not amidated. Belongs to the paralithocin family.
