Structure of a type IV secretion system core complex encoded by multi-drug resistance F plasmids
Abstract
Bacteria conjugatively transfer DNA through type IV secretion systems (T4SSs). Here, the authors report the structure of a T4SS outer-membrane core complex (OMCC), revealing how a distinct C13:C17 symmetry mismatch exhibited by peripheral ring and central cone substructures is accommodated.
