Figure 2
(a) Schematic view of the structure of PA2169, a protein of unknown function. The dotted line indicates the flexible loop that is not well defined in electron density. (b) Surface representation of PA2169 with residues colour-coded according to sequence conservation from white (not conserved) to cyan (invariant). (c) View of the potential metal-binding site in PA2169 comprising residues Glu102, Asp106 and His139.  [article HTML]
