Dear all,

working format to users in addition to using it at e.g. the PDB, because

Tim,
Having not read Gerard Kleywegt's announcement, and not considering myself a
programmer, I have to disagree with the majority of your statement. Yes, using
grep on mmcif files is awkward (but petfectly possible); awk on the other
hand works much better. It's actually more of a pain to
I just hope that one day we all will be discussing a sort of universal API to
read/write structural information instead of referencing to raw formats, and
routines to query MX data, which would be more appropriate than grep (would
many SB students/postdocs use grep these days? but many if them
Hi Tim,
I just downloaded GroEL entry 4KI8 in pdb format and cid format from
RSCB. The PDB format was 4.7Mb and the CIF format was 5.9Mb, doesn't seem such
a big difference to me ? Which example were you looking at ?

Dear All,
Sorry for the off-topic post. I am looking to overproduce a protein
for crystallography purposes in /Saccharomyces cerevisiae/. Nobody in my
lab has ever overproduced a protein in yeast before so I need to try
producing a control protein first. Does anybody know an /E. coli /or
We used expression of full length beta-galatosidase in yeast for a lab
class. Simple to purify, simple to assay.

Hi Ian,
yes, also as Andrew pointed at, I meant to refer to the ration of xml
vs. cif rather than cif vs. PDB.
My worry was that future versions of programs like refmac, phenix, or
buster-TNT would only write large files (in xml-format) and no more
Tim,
PDB file format is good because of its simplicity and that's perhaps it.
However, it cannot accommodate wealth of information that is available at
the end of refinement. Of course one can keep creating remarks for PDB file
etc but I guess mmCIF is just a better way of doing it rather than
I always assumed there was a broad consensus that the PDB format was
ancient and by now profoundly rubbish.
Ho hum, live and learn.

Questionable practice is writing an interpretation program for
operations that can be handled simply at the command line. Programs
that use the API that Eugene implicitly refers to are no panacea, e.g.
Coot has strange restrictions on things like changing the chain label
that can be fixed in

There seems to be some kind of a gap between users and developers as far the eagerness to abandon PDB in favour of mmCIF. I myself fully agree with Jeffrey about the ease of manipulating
PDB's during work, particularly when encountering unusual circumstances (and there are many of those, as we
