Figure 2. Structure of SARS ADRP
(A) Ribbon
representation of the SARS nsP3 ADRP monomer. The two
glycine-rich loops are shown in yellow. Secondary structures are
colored from blue (N) to red (C terminus). Helices are numbered
H1-H6, and b strands are numbered from 1 to 8.
(B) The SARS
ADRP dimer observed between the B and D subunits in the
asymmetric unit. The four conserved segments are colored red in
each subunit; the conserved histidines and asparagines at the
active site are shown as ball-and-sticks.
