a Top view of the OMCCIR with the surface representation of five ASUs, the central ASU-0IR and its interacting ASUs +1, +2, −1 and −2. The TraB and TraV of ASU-0IR are colour coded as described in Fig. 2a. TraB of the +1, +2, −1 and −2 ASUs are coloured in light green, dark green, light blue and dark blue, respectively, and TraV of the +1, +2, −1 and −2 ASUs are coloured in brown light brown, pink and light pink, respectively. b Side view of the five ASU in cartoon representation colour coded as described in ‘a’. c Surface area buried in ASU-0IR by interacting protein chains. d Mapping of interacting chain-ASU interactions onto ASU-0IR. The interactions made by the neighbouring ASU chains are mapped onto ASU-0IR using the same colour code as ‘a’. e Top view of the OMCCOR with the surface representation of three ASUs, the central ASU-0OR and its interacting ASUs +1 and −1. The TraB, TraK and TraV of ASU-0OR are colour coded as described in Fig. 2a. TraB of the +1 and −1 ASUs are coloured as dark blue and light blue respectively, TraK1 of the +1 and −1 are coloured in light green and dark green, TraK2 of the +1 and −1 are coloured in dark brown and light yellow, respectively, TraV1 of the +1 and −1 are coloured in dark pink and light pink, TraV2 of the +1 and −1 are coloured in light orange and brown, respectively. f Side view of the three ASU in cartoon representation colour coded as described in ‘e’. g Surface area buried in ASU-0OR by interacting protein chains. h Mapping of interacting chain-ASU interactions onto ASU-0OR. The interactions made by the neighbouring ASU chains are mapped onto ASU-0OR using the same colour code as ‘e’.
