| Comments | The enzyme, characterized from the bacterium Escherichia coli O55:H7, participates in the biosynthesis of an O-antigen. The reaction involves anomeric inversion, and does not require any metal ions. The enzyme is highly specific towards the acceptor, exclusively recognizing lacto-N-biose, but can accept GDP-L-fucose as the donor with almost the same activity as with GDP-¦Â-L-colitose. |

| History | |
| Reactions | GDP-beta-L-colitose + beta-D-galactopyranosyl-(1->3)-N-acetyl-D- glucosamine = Gdp + alpha-L-colitosyl-(1->2)-beta-D-galactosyl-(1->3)-N- acetyl-D-glucosamine. |
