<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Assembles together with p132 to form the three L-shaped long tail fibers and probably the collar structure at the junction between the tail tube and the conical tail tip (PubMed:24198424). The three L-shaped long tail fibers recognize the host lipopolysaccharides that serve as adhesion receptor for virus entry (PubMed:7045389). Each fiber consists of a thin proximal rod of about 30 nm connected by a hinge to a thicker distal part of about 47 nm (PubMed:24198424).2 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence.
