foldit doesn't do electron densities and I don't recall if there are
any puzzles in it that mention active sites/docking (it's been more
than a year since I "played" it), but it's worth a mention.

James,
I would like to recommend the free ICM-Browser

structural biology and it is easy to make fun and interesting fully
interactive 3D slides and animations of protein structures.
The students can view the fully inter
Does trimethyl lead tend to lose the Me in aqueous buffers?
A colleague is preparing to deposit a 2.9A structure that
was refined against the TML derivative (higher resolution than native).
Since the Pb was added as trimethyllead, the first inclination is
to report the heavy atoms as TML, ligand

I've given a couple talks/demos to HS students. As much as I love enzymes, I
found it more effective to show structures of proteins binding to other
biological molecules (not just other proteins). I typically show

Hi,
I think that spdbv (deepview) and the tutorial has some of what you need. The program is very simple to implement on any Mac or PC, although it's not the nicest program to use in the long run. It'll take you 5 minutes to install and test the features you'd
like from the tutorial.
Cheers
Hi-
I am trying to help my former chemistry teacher set up a demonstration of
protein structure for her class. I'd like to include electron density maps,
and maybe show an enzyme active site. Are there suggestions from the BB on
the easiest way to do this? Would pymol be the program of choice, or
After quick look at the manuscript: It is applicable to sparse signals (i.e.
number of non-zero elements is not whole space). It would be applicable to
inverse FFT after density modification and gain would not be that much.

I don't know of a cheat-sheet, but I find the "Introduction to Protein

common folds.

Hello Everyone,
Does anyone know of a quick (yet somewhat reliable) sort of cheat-sheet/quick
reference sheet with the more common folds with an illustrative example?
The problem is however, that the coffee break is lost in the noise of this FFT.

New Fourier transform algorithm supposedly improves the speed of Fourier
transforms get up to "a tenfold increase in speed" depending upon
circumstances. Hopefully this will get incorporated into our refinement
programs.

Hi all,
There is a good news and it is that we have got crystals this morning which
have diffracted upto 2.5 ang at home source and data collection is going
on. I hope this solves the problem though the not so good anomalous signal
at home source will probably make SAD phasing difficult. However t
