[Chimera-users] Multiscale model of RNAP : fibrous aspect

[Sacha De Carlo]

Hi,

What do you mean by difficulties of creating surfaces?
I speak for a person coming from the cryo-em world, that T4 RNAP surface pretty much looks like a 4A 3D reconstruction based on cryo-EM data. Compare with Ludtke's GroEL structure at about 4 A (Ludtke et al., 2008, Structure 16:441-448).

Maybe compare with surface renderings of the 4A X-ray structure of holoenzyme by Murakami (Science, 2002) or the first x-Ray structure of RNAP2 at ~5A by Darst?
 
I am sure that the Chimera team will tell you more about how the surface is calculated, but it looks correct to me.

Sincerely,
- S
