That's a really old paper. You can purchase the lysozyme from Hampton
Research and it's fine. The recipe is available from the Hampton Research

Grow them a low temp and you can stop them when they are the right size.

Specifically, in this paper you will find that the crystallization behavior of

Thanks for the quick response! I downloaded the newer version of COOT, and
it works perfectly now. Thanks for the help!

If you simply want a list of modified residues, here is one that I
compiled a while ago. More details on each can be found at LigandExpo.
'0CS' => 'ALA', '0NC' => 'ALA', 'AA3' => 'ALA',
'AA4' => 'ALA', 'ABA' => 'ALA', 'AHO' => 'ALA', 'AHP' => 'ALA', 'AIB' =>

Does anyone out there have a protocol of growing HEWL crystals that are
all 50-100 microns wide? I gave this project to a summer student
recently, thinking it would be easy, but it is turning out to be more

crystals. Yes, I
Dear All,
Is there a simple way (or already an existing list) to extract/parse from
the heterodictionaries or monomer libraries which 3-letter symbols are

solvent molecules etc)?

I am trying to refine a protein-DNA structure, and I am having
difficulties refining the DNA using COOT. I used the ccp4i Phaser
program to molecular replace the protein and DNA simultaneously (there
are solved crystal structures of the free protein and a similar DNA
bound to another protein),
Hi Brittney,
DNA is pretty standard so the restraints should be in the dictionary. Perhaps
the DNA in your model has non-standard residue names (PDBv2). Are your bases
called DT, DA, etc? Do your atom names have "*" or "'"?

A smart polysaacharide autobuilder mindful of geometry and biology (no

Yu,
There is a parity analysis in dataman (a USF program) for example.
You have to take into account that the sigmas are generally estimated
assuming a unimodal intensity distribution, which is no longer true in
the pseudo-symmetric case. In practice this means that the sigmas of

Hi Kim and Kevin,
Even then you can have chirality inversions during real-space refinement, which
would destroy the SWEET input model from. There is no substitute for common

Yes but it is easier to take the sweet model for the required sequence
and fit that to density rather than do it residue by residue
which will lead to glycan structures unknown to the source

Dear Kim,
I asume that Kevin plans to build in electron density maps. As far as I
can see Sweet will produce a model unhindered by experimental data.

superpose has two options undfer CCP4i.
Choose match numbered residues ( not SSM)
Then you must give two files to match - in your case that means naming
your model twice.
Then say you want to match residues 1 to 20 Chain A to residues 1 to 20
CHAIN B tever span you want to fit.
