<p> This entry represents a core 32-residue region of a class of bacterial protein repeats, which are found from one to thirty times in each protein. Most proteins with a copy of this repeat have domains associated with membrane autotransporters (<db_xref db="INTERPRO" dbkey="IPR005546"/>, <db_xref db="INTERPRO" dbkey="IPR006315"/>). The repeats occur with a periodicity of 60 to 100 residues and may have a beta-helical structure.</p> Autotransporter-associated beta strand repeat
