Figure 3. Binding pocket for the donor substrate. UDP,
GalNAc and Mn^2+ are shown in ball-and-stick representation in
the same colors as for Figure 2. Amino acid residues interacting
with the donor substrate are shown in a line representation
(carbon atoms, green). Hydrogen-bonding interactions are shown
as black broken lines. The coordinate bonds to Mn^2+ are
represented as red broken lines. The oxygen atom of water
molecule that coordinates the Mn^2+ is labeled with Wt. (a) and
(b) Two views corresponding to those shown in Figure 2(a) and
(b), respectively.
