It is easy to become enamored with cartoon molecular structures, and it is getting increasly trivial to generate these images without any real data to support them. With that in mind, peruse these structures*, depicting a nanotube synthase, a rotary motor, and a cube-shaped DNA scaffold:
Of these three structures, only one has an actual crystal structure that can be found in the PDB, one is pure speculation, and the third has been synthesized and characterised, but there is no atomic-resolution structural data so far available.
Can you tell which is which?
* Reference in an upcoming post, I don’t want to give the answer away.
