Distribution of MDHS, conserved water molecules and ePHOGSY NMR signals in the Sso7d structure. Ribbon representation of Sso7d [PDB:1C8C] showing the ePHOGSY signal intensity, the darker the blue, the stronger the signal; grey indicates regions where no signal was detected. The MDHS are shown in yellow; the plotted mesh iso-surfaces were at level 2.0. The water molecules that were found to be conserved in the available crystal structures are shown as purple spheres.
