MrpH, a new class of metal-binding adhesin, requires zinc to mediate biofilm formation
Fig 5
The top surface of MrpHntd is highly positively charged.
Side (left) and top (right) views showing the electrostatic surface of MrpHntd. A crevice extending from the ligand-binding site (tartrate displayed as a stick model) could serve as a binding site for an extended, possibly negatively charged, ligand and/or receptor. Alternatively, the positively charged surface could facilitate approach to negatively charged surfaces without being directly involved in binding. Positive surfaces are blue, neutral surfaces are white, and negative surfaces are red.
