Comparison of amino acid sequences of cloned H. pylori CHLαGcT (Hp), H. felis CHLαGcT (Hf), and putative CHLαGcTs from H. hepaticus (Hh), H. mustelae (Hm), and H. acinonychis (Ha). Identical amino acid residues are indicated by closed boxes. Adapted from Lee, H.; Kobayashi, M.; Wang, P.; Nakayama, J.; Seeberger, P.H.; Fukuda, M. Biochem. Biophys. Res.
