NMR structure of the R-module from AlgE4. The R-module folds into a right-handed parallel beta-roll. Its overall shape is an elongated molecule with a positively charged patch that interacts with the substrate. Titration of the R-module with thulium indicates possible calcium binding sites in the loops formed by the nonarepeat sequences in the N-terminal part of the molecule. Calcium binding is important for the stability of the R-module. Calcium ions can be incorporated in these loops without structural violations and changes | Azotobacter vinelandii |
