Crystalization Experiments
Details THESE COORDINATES ARE FOR THE BINARY COMPLEX WITH HYDROGEN SULPHITE (HSO2OH-). THIS COMPLEX WAS OBTAINED BY SOAKING WITH LIPOAMIDE AND SODIUM DITHIONITE. THE RESULTING ELECTRON DENSITY DOES NOT INDICATE THAT LIPOAMIDE IS BOUND. ON THE OTHER HAND, AN EXTRA DENSITY PEAK IN THE CATALYTIC CENTER IS INTERPRETED AS HSO2OH-. THE LATTER MIGHT BE DERIVED FROM THE HYDROLYSIS OF DITHIONITE. SEE REF 3.
