Type III secretion system effector delivery regulator TyeA (IPR015144)

Short name: T3SS_TyeA

Overlapping homologous superfamilies

Domain relationships


This domain is composed of two pairs of parallel alpha-helices, and interacts with the bacterial protein YopN via hydrophobic residues located on the helices. Association of TyeA with the C terminus of YopN is accompanied by conformational changes in both polypeptides that create order out of disorder: the resulting structure then serves as an impediment to type III secretion of YopN [PMID: 15701523].
