Fig. 5. Stereoviews of the catalytic site and surrounding
hydrogen-bonding network. a and b, the calcium-free and
calcium-bound forms of the S. violaceoruver PLA[2],
respectively; c, N. naja atra PLA[2] (7). The hydrogen bonds are
shown by black broken lines. The numbers in b and c show the
distance (Å) between calcium(II) ion and the His64 N 1 (the
His48 N 1 in N.
naja atra).
