mutant H188K in the presence of alpha-ketoglutarate and pyridoxal 5'-phosphate, to 1.9 A resolution. The observed electron density is consistent with the formation of a geminal diamine intermediate formed by the reaction of an internal aldimine with glutamate | Escherichia coli |
Protein Variants | Comment | Organism |

H188K | the active site histidine has been replaced with a lysine. The electron density reveals that the geminal diamine, a tetrahedral intermediate in the formation of pyridoxamine 5'-phosphate from pyridoxal 5'-phosphate, has been trapped within the active site region | Escherichia coli |
