| - | The apo crystal structure of CTX-M-9 beta-lactamase has been determined to, 0.88 A at pH 8.8. This unusually clear picture of proton positions and, residue interactions supports the role of Glu166 as the general base for, the controversial acylation step of class A beta-lactamase catalysis. The, ability to distinguish low-energy conformations sampled by the enzyme, allows us to link the two conformations of Lys73 to different protonation, states of Glu166. | ||
