*9.B.40.1.3









Conjugal transfer protein, TraY, of 886 aas and 8 TMSs in a 4 + 4 TMS arrangement, with a large hydrophilic domain between the two TM domains.  Involved in DNA recognition and transfer (Taki et al. 1998; Lum and Schildbach 1999; Williams and Schildbach 2007).  The conjugative transfer of antibiotic resistance genes in S. enterica Typhimurium under intestinal conditions has been examined (He and Ahn 2014).
