CC   -!- FUNCTION: Major structural protein of the hrp pilus, which is a
CC       component of the type III secretion system (TTSS, Hrp secretion system)
CC       required for effector protein delivery, parasitism, and pathogenicity.
CC       The hrp pilus functions as a conduit for protein delivery into the host
CC       cell. Also, affects the expression of TTSS-associated genes. Required
CC       for full expression of genes that encode regulatory, secretion, and
CC       effector proteins of the TTSS. HrpA-mediated gene regulation apparently
CC       is through effect on the mRNA level of HrpR and HrpS (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}. Fimbrium {ECO:0000250}.
CC       Note=Extracellular and secreted via type III secretion system.
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the HrpA type 1 family. {ECO:0000305}.
