Protein

Long tail fiber protein p37

Gene

37

Organism
Enterobacteria phage K3 (Bacteriophage K3)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Structural component of the distal-half tail fiber. It constitutes the part of the long tail fibers that recognizes the bacterial receptor.

Miscellaneous

The two Gp37 protein chains run in parallel, the length of the distal half-fiber, with the amino end near the center kink of the fiber and the carboxyl end at the distal tip. The other polypeptides are distributed uniformly along the length of the distal half-fiber.
