Figure 16
N–N methyl shift in a pyrimidinone. The methyl group, as expected, would clash with the guanidinium group of Arg127 (marked in red). The pyrimidinone cannot be rotated by 180°, as this would swap the positions of the exocyclic S and O atoms. The position of the S atom (yellow), however, is clear from the electron density. |
