CC   -!- FUNCTION: Structural component of the distal-half tail fiber. It
CC       constitutes the part of the long tail fibers that recognizes the
CC       bacterial receptor (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: The distal half-fiber contains two molecules each of Gp36 and
CC       Gp37 and one molecule of Gp35. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC   -!- MISCELLANEOUS: The two Gp37 protein chains run in parallel, the length
CC       of the distal half-fiber, with the amino end near the center kink of
CC       the fiber and the carboxyl end at the distal tip. The other
CC       polypeptides are distributed uniformly along the length of the distal
CC       half-fiber.
CC   -!- SIMILARITY: Belongs to the tail fiber family. {ECO:0000305}.
