CC   -!- FUNCTION: Curlin is the structural subunit of the curli. Curli are
CC       coiled surface structures that assemble preferentially at growth
CC       temperatures below 37 degrees Celsius. Curli can bind to fibronectin.
CC       The minor subunit is the nucleation component of curlin monomers (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Fimbrium. Note=Part of the curli surface
CC       structure.
CC   -!- SIMILARITY: Belongs to the CsgA/CsgB family. {ECO:0000305}.
