This entry represents the head completion protein (gp16) found in Siphoviridae bacteriophages. This protein functions as a stopper in the portal-tail connector complex, locking the viral DNA inside the capsid. During infection, it undergoes a conformational change, opening by a diaphragm-like motion to allow the genome to exit the capsid through the tail tube to the host cell. The protein also functions as a docking platform for the preassembled tail. The connector complex is essential for stable viral particle assembly and controlled genome release during host infection.
