protective antigen is a muscled henchman

Categories: Comparisons

An example of metaphor in popular science writing:

"Central to its success is a potent three-part toxin made up of protective antigen [PA], lethal factor [LF] and oedema factor EF [oedema factor]. … PA is the muscled henchman of the group that attaches to the surface of our macrophages and gathers EF and LF to its side."
