NON-ACTIVATED SPINACH RUBISCO IN COMPLEX WITH ITS SUBSTRATE RIBULOSE-1,5-BISPHOSPHATE
Overview
The three-dimensional structure of the complex of ribulose, 1,5-bisphosphate carboxylase/oxygenase (rubisco; EC 4.1.1.39) from spinach, with its natural substrate ribulose 1,5-bisphosphate (RuBP) has been, determined both under activating and non-activating conditions by X-ray, crystallography to a resolution of 2.1 A and 2.4 A, respectively. Under, activating conditions, the use of calcium instead of magnesium as the, activator metal ion enabled us to trap the substrate in a stable complex, for crystallographic analysis. Comparison of the structure of the, activated and the non-activated RuBP complexes shows a tighter binding for, the substrate in the non-activated form of the enzyme, in line with, previous solution studies. In the non-activated complex, the substrate, triggers isolation ... [(full description)]
