Dear All,
Thanks for the reply.
I will try process and refine the data again, will see if it improves.
Thanks again to all.

There isnt much information here!
Funny that 3 chains are poor - does that mean one and a half heterodimers?
I presume you have checked spacegroup? Zanuda will test to see if any
higher symmetry is present..

Dear Eleanor,
Thanks for the suggestion, I just checked on the Zanuda program, it is also
giving P1 as the best possible spacegroup for the molecule.
and by not refining well, I meant for the electron density which is broken at
many places at main chain, and poor electron density for the
FYI, I do know of one example of a solved structure where some of the
molecules in the ASU are poorly defined. In 1EKJ, 4 of the 8 molecules
in the ASU have low B-factors (mid 30s) and 4 have high B-factors
(50s-60s). In the unit cell these layers alternate. It is possible, if
everything else
You may also get some insights from TLS refinement.

Dear All,

Francis, we used molrep for the structure solution. As I told that we already
have the structure of the same protein, but a variant. So, we used its single
chain (heteromer) as a model for molecular replacement.
and Eleanor, I deleted once that
