3D-structure of H:gm. Atomic model of the Salmonella enterica flagellar antigen H:gm (507 aa) generated with Phyre2 (Protein Homology/Analogy Recognition Engine) [26] and drawn in PyMOL. The protein forms a tubular like structure with the N- and C-terminal ends in close proximity to each other. The region corresponding to H:gmd (aa 254–351) is highlighted in cyan.
