Model of the complete extramembrane part of LdtMt2 from M. tuberculosis. The model was derived by superposition of the B domains common to the structures of the AB and BC modules. The maximal distance between the membrane and the catalytic site, where cross-link formation in the cell-wall peptidoglycan by LdtMt2 can occur, can be approximated to at least 80-100 Å.  [article HTML]
