You will need to add the "link" line to the PDB file so the software recognises the covalent bond. See the pdb file for 6U6K Hope this helps J From: CCP4 bulletin board On Behalf Of Jiang Xu Sent: Thursday, 7 July 2022 10:15 AM To: CCP4BB@JISCMAIL.AC.UK Subject: [ccp4bb] circular peptide stru

2022-07-06 Thread Jiang Xu
Hello everyone, I have a peptide that forms a peptide bond between the N terminal and C terminal. I used X-ray crystallography to solve the structure and found the N and C terminals are pretty close to each other with extra electron densities clearly showing that they form a peptide bond. Howev

Hi Carmien, It appears to me that the dewars in your first link are those made by Taylor Wharton. You can do a search with that name and hopefully find less expensive options. We've used them for many years and they are good. Another one, you could try, is VME https://mvebio.com/aluminum-dewars/ We
