GPHN and infection: The capsidis mostly made up of a major capsid precursor, gpN, with accessoryproteins gpO and gpL acting as scaffold and completion proteins, respectively.The tail fibers are made from gpH, with gpG required for assembly.The tail fibers (gpH) and the spike (gpV) have been shown to mediatethe adsorption and infection of P2 into a host,34 although the tail fibers alone are used to bind to thetarget first, while the spike subsequently binds to other receptorsin the bacterial membrane to strengthen the binding.35
