Model reconstructions of PgdS in solution.

<p>(A) Model reconstructions of PgdS in solution. Right: <i>ab initio</i> models from DAMMIF model; left, superposition of DAMMIF and CORAL model. The missing loops are represented as dummy residues colored cyan. Two orientations are shown. The domain 1, 2 and 3 are colored in green, blue and yellow, respectively. The relative positions of the N/C terminal and the functional catalytic core are also labeled. (B) Superimposed of two models of PgdS in a compact state (pH 5.0) and in an extended state (pH 8.0). The domain 2 and domain 3 are colored in grey, whereas domain 1 are colored in yellow (compact state) or blue (extended state).
