NameO-antigen polymerization/export system wzx/wzy/wzz
DescriptionThe Wzx/Wzy/Wzz system trnasports the O-antigen monomers from the cytoplasmic face of the plama membrane to the periplamic face and then polymerizes the monomers to form the mature O-antigen. The Wzx protein is the transporter (aka the flippase), Wzy is the polymerase and Wzz is the chain length determinant protein.
