WebThe Hly translocator complex of Escherichia coli catalyzes type I secretion of the toxin hemolysin A (HlyA). In this complex, HlyB is an inner membrane ABC (ATP Binding … WebThis model represents the adaptor protein between the ATP-binding cassette (ABC) protein of the inner membrane and the outer membrane protein, and is called the membrane fusion protein. This model selects a subfamily closely related to HlyD; it is defined narrowly and excludes, for example, colicin V secretion protein CvaA and multidrug efflux proteins.

WebAn efficient trans-complementing HlyB/HlyD system was only obtained from the pHLy152-encoded hly determinant when the regulatory hlyR element was provided in cis. Secretion of the PhoA-HlyA fusion protein did not interfere with the secretion of HlyA even when the fusion protein was induced to a high level. WebThe C-terminal domain of HlyA can also be used to promote the secretion of several other E coli and mammalian proteins. HlyD and HlyB are essential for translocation of HlyA to the medium and we propose that these proteins form a transenvelope complex which initially binds the HlyA signal followed by transport of HlyA to the medium. gareth pierce and daniel furner
