|Title:||Preliminary X-ray Diffraction Studies Of Rabbit Muscle Triose Phosphate Isomerase (tim).|
Ferreira, S T
Leite, N R
|Abstract:||Triose phosphate isomerase (TIM) is responsible for the interconversion between GAP and DHAP in the glycolytic pathway. Two crystal forms belonging to space group P2(1)2(1)2(1) were obtained by the hanging-drop method and were designated A and B. Synchrotron X-ray diffraction data were collected for both forms. Form A had unit-cell parameters a = 65.14, b = 72.45, c = 93.24 A and diffracted to 2.25 A at 85 K, whereas form B had unit-cell parameters a = 73.02, b = 79.80, c = 172.85 A and diffracted to 2.85 A at room temperature. Molecular replacement was employed to solve the structures, using human TIM as a search model. Further refinement of both structures is under way and is expected to shed light on the recently reported conformational studies for rabbit TIM.|
