Figure 3
Hydrogen-bonding network in SodA2. Gln150 hydrogen bonds through Tyr36 and His32 to a tyrosine from the other chain (cyan). In the case of SodA1, Gln150 makes a further hydrogen bond with Trp132 (see text), whereas in SodA2, as shown here, this interaction is with Tyr132. Mn is represented by a purple sphere and waters are in red. This figure was drawn in PyMol (DeLano, 2002). |
