Fig. 4.
MD structures of the truncated heterodimers.
The intact monomer is blue, the truncated one is cyan, the substrate is green, and the flexible loop is magenta. (A) MD1 calculation; the truncated monomer is complexed with an intact monomer without substrate. (B) MD2 calculation; the truncated monomer is complexed with an intact one with substrate bound. The distances between the Cα (nearest) atoms of Ala73 of the truncated monomer and Cα atoms of Gly171 or Thr172 of the loop in the intact monomer are indicated by A and B, respectively.
