A	PF03562	MltA specific insert domain (MltA)	MltA specific insert domain	This beta barrel domain is found inserted in the MltA a murein degrading transglycosylase enzyme [1]. This domain may be involved in peptidoglycan binding.	Domain
A	PF06725	3D domain (3D)	3D domain	This short presumed domain contains three conserved aspartate residues, hence the name 3D. It has been shown to be part of the catalytic double psi beta barrel domain of MltA [1].	Domain
