Cartoon representation of CpGH84 potential +1 subsites. CpGH84C (in green) in complex with PugNAc (in pink, PDB code 2CBJ) has been aligned with CpGH84A (in purple), CpGH84B (in yellow) and CpGH84D (in blue). The residues for CpGH84s potentially involved in the description of a + 1 subsite are shown as sticks, as well as CpGH84C catalytic residues. The subsites are labeled in red.
