This domain is found in Adhesin from Haemophilus influenzae (Hia) and similar proteins predominantly from proteobacteria. Hia is a trimeric autotransporter that mediates bacterial adherence to the respiratory epithelium. This protein shows a modular architecture with repeats of structurally distinct domains. This entry represents one of the Trp-ring domains [1].	Domain
