The mycobacterial cell wall presents significant challenges to mycobacteriophages--viruses that infect mycobacterial hosts--because of its unusual structure containing a mycolic acid-rich mycobacterial outer membrane attached to an arabinogalactan layer that is in turn linked to the peptidoglycan. Although little is
