Overall structure of PA1611REC. (a) Ribbon diagram (green) illustrating the secondary-structure elements in PA1611REC. The β-strands and α-helices are numbered sequentially β1 to β5 and α1 to α5, respectively, from the N- to the C-terminus. Mg2+ is shown as a light green sphere. (b) Stereoview of the overall structure of PA1611REC with Mg2+ in the active-site cleft (PA1611REC-Mg2+). |
