FunctionMINE_ECOLI Prevents the cell division inhibition by proteins MinC and MinD at internal division sites while permitting inhibition at polar sites. This ensures cell division at the proper site by restricting the formation of a division septum at the midpoint of the long axis of the cell.[1] Evolutionary Conservation Check, as determined by ConSurfDB.
