Figure 3.
Figure 3 (a) A stereoview of the recombinant bovine PLA2 enzyme showing the active-site cleft and the inhibitor TSA (ball and stick). Calcium ion is shown as grey circle and the disulfide bonds are shown. (b) The above view has been rotated (rotation -115° in y and -30° in x), which shows the atoms of the TSA inhibitor in the active site. Note the calcium-binding loop is above the inhibitor. The figures were produced using the program MOLSCRIPT (Kraulis, 1991[Kraulis, P. J. (1991). J. Appl. Cryst. 24, 946-950.]).
