[ccp4bb] pdb format problem of an intermolecular disulfide bond from different symmetric units

[Zhongzhou Chen]

Hello, everyone，<o:p></o:p>&nbsp;Recently, we found an intermolecular disulfide 
bond from different symmetric units. I want to define it to refine, such as by 
refmac5. &nbsp;I know the regular format of a disulfide bond in the same 
symmetric unit and show it as below.<o:p></o:p>&nbsp;SSBOND&nbsp;&nbsp; 1 CYS 
A&nbsp; 115&nbsp;&nbsp;&nbsp; CYS A&nbsp; 191<o:p></o:p>&nbsp;My question 
is：&nbsp;How to define a disulfide bond from different symmetric 
units?<o:p></o:p>&nbsp;Best,<o:p></o:p>zhongzhou chen
