Figure 1.
Figure 1. a: Stereo view of the 2Fo-Fc difference electron density map around the region of the P-loop, contoured at 2 . Clear residual electron density present in front of the P-loop was interpreted as a bound SO4-ion (ball and stick, Sulphur: green, Oxygen: red). b: Ball and stick representation of the SO[4]-ion bound to the P-loop. c: Ball and stick representation of the SO[4]-ion bound at the opposite site of the P-loop in the putative phosphate accepting substrate binding groove.
