Computational protein models of two pyrophosphatases (i.e., PPa1 encoded by the AMG ppa 1 and PPa54 encoded by the AMG ppa 54) and one alkaline phosphatase (i.e., PhoD22 encoded by the AMG phoD 22). Helices and sheets are colored in a rainbow scheme (from the N terminus in red to the C terminus in blue). Detailed information on individual computational protein models is provided in Supplementary Data 12.
