Dear users, I had posted this question already but in a different context.One of the Se-Met derivatised protein that we have solve is a homodimer (with 4 MET in the chains that crystallised) of which one chain has 3 MSEresidues, while the other chain has only 2 MSE.Are there any such instances in P

Respected Sir, Thank you for the efforts and nice depiction of the problem. The Dimeric assembly that is solved and the one predicted by PISA is depicted in the attachment. This is the arrangement I wanted to describe. The protein overall appears like a "C". Thanking you With Regards KavyaSince

Thank you Sir for the suggestions. Hi,If, in your case, no possible asymmetric unit can contain A1-B2, then you deposit A1-B1 (or I suppose A2-B2...) and indicate to the PDB (like placing cards in the header cards) the operator to be used (and the subunit it applies to) in order to generate the mos

Dear users, We have a structure which is a homodimer in the asymmetric unit.PISA predicts most probable assembly as a dimer but thisdimeric assembly is different from what is solved (offcoursewe can generate the symmetry equivalent molecule and get that).My question is - is it necessary that we dep
