Figure 6.
Fig. 6. Stereo diagram showing the superposition of the
active site of Cab , P. sativum, and P. purpureum -CAs
including zinc, zinc-coordinating residues, and the conserved
residues differentiating between cab- and plant-type -CA. A, Cab
is shown in yellow; P. sativum -CA is shown
in green. The coordinating water molecule in Cab is shown in
red. B, Cab is shown in yellow; P. purpureum -CA is shown
in blue. The coordinating water molecule in Cab is shown in red.
