 The XopK sequence contains 54% hydrophobic residues and several predicted transmembrane domains. Thus, it is possible this protein is associated with host cell membranes following secretion (Mutka //et al//., 2016) The XopK sequence contains 54% hydrophobic residues and several predicted transmembrane domains.
