Using cartoon view to present the protein secondary structures and tertiary structure is common and we also often see people present some sidechains of particular residues which may be important in some biological roles. In PyMOL, when sidechain atoms are presented in the “sticks mode” with the cartoon*scaffold, we always see the backbone atoms (e.g. [...]

Some cartoon views of proteins shown in PyMOL
Example of cartoon modes of protein shown by PyMOL Example protein: 1UA8, LolA By default, the cartoon mode in PyMOL shows protein structure like this way: We can change the background to white by typing “bg_color white” in the command terminal and also change the color of protein based on types of secondary structures in http://stats.wordpress.com/b.gif?host=kpwu.wordpress.com&blog=76132&post=526&subd=kpwu&ref=&feed=1

[KPWU blog] [PyMOL] DNA?example II
DNA?example II
Follow up previous post, here shows several modes available in PyMOL to display the ribbon/chain of DNA/RNA. Example molecule: B-form DNA PDB code: *2L8Q Running version, PyMOL 1.3 (x11 version on MacOS 10.6) The previous version use “oval” to show the ribbon of DNA. Here are some other ways to show the ribbon: 1. default http://stats.wordpress.com/b.gif?host=kpwu.wordpress.com&blog=76132&post=446&subd=kpwu&ref=&feed=1

[KPWU blog] [PyMOL] example of DNA
example of DNA
Several private emails request me to show some examples of DNA/RNA using PyMOL. I am not familiar with commands related to nucleic acids in PyMOL because I never have chance to study DNA/RNA. I made some posts few years ago just for fun. Here is a step-by-step re-cap I make followed by our old post. http://stats.wordpress.com/b.gif?host=kpwu.wordpress.com&blog=76132&post=429&subd=kpwu&ref=&feed=1

[KPWU blog] [PyMOL] use of ?ray_trace_mode?
use of ?ray_trace_mode?
I do like a command called “ray_trace_mode” in PyMOL because different modes can generate different light and color effects on the structure I want to express to readers/students. Here is a quick examples of the effect on different modes. The structure I use at here is LolA which PDB code is 1UA8. 1. ray_trace_mode 0 http://stats.wordpress.com/b.gif?host=kpwu.wordpress.com&blog=76132&post=407&subd=kpwu&ref=&feed=1

[KPWU blog] PyMOL-electrostaic surface view
PyMOL-electrostaic surface view
To make electrostatic surface view of protein using PyMOL, two ways are often suggest. One option is using ABPS to generate the electrostatic map. Here is one nice instruction at PyMOLwiki using ABPS. Another option is using Delphi developed by Barry Honig group to generate the electrostatic map of protein. I am writing a note http://stats.wordpress.com/b.gif?host=kpwu.wordpress.com&blog=76132&post=322&subd=kpwu&ref=&feed=1

[Question from NMRWiki Q&A forum] Aromatic sidechain assignment pulse sequences for Varian?
Aromatic sidechain assignment pulse sequences for Varian?
Hi, someone asked a similar question before, but I'd like to know:
Are there readily available varian pulse sequences that help assign aromatic side-chains? Maybe there is something like that in Biopack or elsewhere?
Thanks a bunch! M.
