Function

WAC_BPT4 Chaperone responsible for attachment of long tail fibers to virus particle. Forms the fibrous structure on the neck of the virion called whiskers. During phage assembly, 6 fibritin molecules attach to each virion neck through their N-terminal domains, to form a collar with six fibers ('whiskers').

Publication Abstract from PubMed

C3-Symmetric trimesic acid scaffolds, functionalized with bromoacetyl, aminooxyacetyl and azidoacetyl moieties, respectively, were synthesized and compared regarding their utility for the trivalent presentation of peptides using three different chemoselective ligation reactions, i.e. thioether and oxime formation, as well as the "click" reaction. The latter ligation method was then used to covalently stabilize the trimer of foldon, a 27 amino acid trimerization domain of bacteriophage T4 fibritin, by linking the three foldon monomers to the triazido-functionalized trimesic acid scaffold. This reaction dramatically enhanced the thermal stability of the trimer, while maintaining the correct fold, as demonstrated by CD spectroscopy and X-ray crystal structure analysis, respectively, of the foldon-scaffold conjugates.
