Metamorphic proteins. (a, b)Side-by-side comparison of alternatively folded subunits of the DUF74 pentamer (PDB entry 1vr4
). Chain A and chain D (b) are coloured according to their secondary structure. The adjacent subunits are coloured as follows: chain B, light blue; chain C, magenta; chain E, pink. (c, d) Side-by-side comparison of the Sfri0576-like family structures 2q3l
(c) and 2ook
(d). The equivalent nonpolar residues that are exposed on the 2q3l
surface and buried in the 2ook
core are shown in stick representation. |
