Figure 3. A, Sequence alignment of the d subunit of g
complex and of DNA polymerase IV b-binding peptides with the
corresponding consensus sequence.[12.] The most conserved
residues are highlighted in blue and the red lines delimit
sub-sites 1 and 2 (see Results and Discussion). B, Schematic
representation of the b-binding pocket. Peptide P16 is drawn in
red, highly conserved b residues are boxed in green and less
conserved residues in open boxes. Green, black and open circles
identify b residues interacting with the most conserved residues
of peptide P16, i.e. residues L16, L14 and Q11, respectively.
Green and white bars on the right identify the conserved and
less conserved parts within the two sub-sites, respectively.
