Clan: O-anti_assembly (CL0499)

Summary

O-antigen assembly enzyme superfamily Add an annotation

This superfamily is characterised by a group of bacterial proteins that lie in the membrane. The families are all enzymes involved in the assembly of O-antigen lipopolysaccharide, and include O-antigen flippase, polymerase and ligase, the flippase being the putative transporter [1].

This clan contains 5 families and the total number of domains in the clan is 7437. The clan was built by P Coggill.
