What I usually do for this is make a copy of the PDB file and change all
the atom x-y-z positions to "1.000". Then I use something like
reforigin or my "origins.com" script to shift the original coordinates
via allowed symmetry operations, origin shifts, or perhaps indexing
ambiguities until

I use PISA for the compact molecule construction - it works very well, and
probably should be the default at the end of every MR - it also tries to
choose a sensible symm op which allows assemblies to be generated easily.
But then you would have to think about how to position that assembly as

In this case you know the protein is closely relaed to whatefer contaminer
found, and you have good sequence data, so I agree the next step is blast.
Maybe it is an isozyme of the structure used.
In cases where you solve an unknown by heavy atom derivatives and have no idea
what it is; and

just a heads up that these will be unavailable from 3pm GMT on Friday 15th

Here is a VERY oldfashioned solution.
Find the centre of mass of your molecule.

Make a mini PDB with the CRYST1 record, and two "atoms" - one at 0 0 0, the
other at the centre of mass with some atom type say C

Wow, pretty cool—you must have solved it to very high resolution to know the
sequence from the structure. I cannot imagine, however, how you got this
contaminant—maybe phage infection of your bacterial culture? Anyway, I agree
with BLAST-ing the sequence, seeing what you get that is closest.
Hello,
Welcome to the club of unexpected results!
You don't provide a lot of background, but based on what you wrote you can:
1. Do a BLAST search using a known part of your sequence to find whether
this sequence has been deposited.
2. Assign the different residues based on the chemical
Dear CCP4bb,
In 2014, I collected a high quality data set from a crystal. But I could not
solve the structure of that crystal because this protein is a contaminate.
Recently, I used StruBE's Contaminer and fortunately got the solution. Thanks
ContaMiner!!! This protein is a contaminate
Dear Tommi,

you can use moleman2, convert coordinates to fractional ones and add or

In case you want to take the symmetry operations into account,
Dear Paul,
Yes thank you. This was the best answer i think. Someone else already also
suggested that also. Coot is very handy indeed.
(Would still be curious of knowing how to find the "closest to origin" copy
otherwise - but this solves my problem)
Thanks to all who responded.
Cheers,
