Functional Information from PDB Data
| site_id | ACT |
| Number of Residues | 1 |
| Details | RESIDUE 69 WAS TREATED AS A GLYCINE DURING REFINEMENT TO AVOID BIAS IN THE INTERPRETATION OF THE DIFFERENCE ELECTRON DENSITY MAP. THE SIDE CHAIN OF RESIDUE 69 WAS INTERPRETED AS AN ALDEHYDE GROUP WITH TWO-FOLD DISORDERED ALDEHYDE FUNCTION (I.E. THE CARBONYL OXYGEN ATOM OCCUPIES TWO DIFFERENT POSITIONS). THE AUTHORS ASSUME THAT THE ALDEHYDE IS IN EQUILIBRIUM WITH ITS HYDRATED FORM, THE GEMINAL DIOL, WHICH IS IN ACCORDANCE WITH THE SHAPE OF THE ELECTRON DENSITY. |
