The binding sites of Magnesium atom in the structure of The Complex Formed Between Tet Repressor and Tetracycline-MG2+ Reveals Mechanism of Antibiotic Resistance (pdb code 2tct). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 2tct structure was solved by W.HINRICHS, C.KISKER, W.SAENGER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below:
Resolution (A) | 10.0-2.1 | Space group | I4122 | a (A) | 68.780 | b (A) | 68.780 | c (A) | 181.450 | alpha (°) | 90.00 | beta (°) | 90.00 | gamma (°) | 90.00 | Rfactor (%) | 18 | Rfree (%) | n/a |
