Bacterial alpha-2 macroglobulin (A2M) are located in the periplasm and may protect the cell by trapping external proteases through a covalent interaction with an activated thioester [1,2]. Macroglobulin (MG) beta sandwich domains appear to play a structural role. This entry represents bacterial MG2 (bMG2) domain which, with MG1, plays the role of a linker associating the main body of A2M to the bilayer [1-3].	Domain
