Popis: | Relative interatomic distances between the NMR nuclei (H-1 and P-31) and the ferric ion of the ATP-Fe-III complex in solution are evaluated by quantitative analysis of the relaxation enhancements. The results show that, at pH 3, N-1 of the purine base is the coordination site rather than N-7. (C) 1999 Elsevier Science Ltd. All rights reserved. |
