pfam01944: SpoIIM (this model, PSSM-Id:396500 is obsolete and has been replaced by 426524)
Stage II sporulation protein M
SpoIIM is on e of four stage II sporulation proteins that is necessary for the forespore inside the mother-cell to be properly internalized through the breakdown of peptidoglycans trapped between the membranes of the septum separating the forespore and the mother-cell. The four proteins working in sequence are SpoIIB, pfam05036, SpoIIM, SpoIIP, pfam07454, and finally SpoIID, pfam08486. D, M and P are in a complex with each other and the complex assembles in a hierarchical manner such that M, which serves as a membrane anchor, recruits P to the septum and P, in turn, recruits D to the septum.
