HiaBD2_N domain of Trimeric autotransporter adhesin (GIN)
HiaBD2_N may represent the GIN domain of the Head region of TAAs - trimeric autotransporter adhesins. Not all TAAs carry this domain; however, in those that do, the GIN in combination with the Trp-ring domain is necessary for adhesion to fibronectin in the host cell.
