Figure 2. Structural comparison of of E3_19 and E3_5. (a)
Stereoview of the superposition of E3_19 (B molecule, brown)
with E3_5 (PDB ID: 1MJ0, blue) in ribbon representations. The
N-and C-termini are labeled for orientation. The two proteins
are practically identical, with the biggest differences being
observed in the C-terminal AR, where E3_5 appears to be more
compact than E3_19. The two E3_19 molecules of the asymmetric
unit are virtually identical (b) H-bonding in the C-terminal AR
of E3_19. Asn156 makes H-bonds to Asp122 (residues in stick mode
in blue). (c) H-bonding in the C-terminal AR of E3_5. Asn158
makes H-bonds to Lys122 and Ala121 (residues in stick mode in
magenta).
