Figure 5. (a) Atom-sphere model of the p10 connector
particle. Colour coding of the side-chains: green for Asn/Gln,
red for Asp/Glu, grey for hydrophobic residues, and dark blue
for Lys/Arg. The model was generated with GRASP.[63] (b)
Molecular surface coloured according to electrostatic potential
(red for negative, blue for positive) belonging to six vicinal
protein monomers generated with GRASP. [63] The position of the
two interior lysine rings (made up by Lys209 and Lys200 of each
monomer, respectively) is indicated. (c) Ribbon plot showing a
longitudinal cut of the connector particle. Note that the
colours of the distal domains are different from the central and
SH3-like domains since they belong to different monomers. A
dsB-DNA molecule is shown traversing the central channel. The
side-chains of Lys200 and Lys209 are indicated. (d) View along
the connector axis with the modelled DNA. The side-chains of
Lys200 and Lys209 are displayed as a balls and sticks.
