Crystal structure of the D183N variant of human Alanine:Glyoxylate Aminotransferase major allele (AGT-Ma) at 1.8 Angstrom; internal aldimine with PLP in the active site

Radiation damage at the active site of human alanine:glyoxylate aminotransferase reveals that the cofactor position is finely tuned during catalysis.
