Fig. 2: Threads form cables of parallel or antiparallel filaments.
From: Electron cryo-microscopy reveals the structure of the archaeal thread filament
a CryoEM map of a thread cable at 13 Å resolution. Atomic models of the thread (in cartoon representation) can be fitted into the map in parallel (b, c) or antiparallel orientation (d). Shape complementarity between parallel and antiparallel threads is very similar (c, d). Glycans (sticks) mediate the interaction between the threads in the cable. A and B are in the same orientation. c and d are rotated by 150° with respect to a and b. Scale bar 40 Å.
