It looks like the density suggests an S-S bond. Perhaps try CME? https://www.rcsb.org/ligand/CME

The condition was optimized from the Morpheus Screen condition D1, so MES/Imidazole pH 6.5, PEG 500MME, PEG20k and a mix of 1,6-Hexanediol, 1-Butanol, 1,2-Propanediol, 2-Propanol, 1,4-Butanediol and 1,3-Propanediol. The data has been cut at 1.7A, with good stats. Has anyone seen anything like this before? what do you think my best bet for modeling this is? and aduct of 1,3-propanediol? It looks too short for 1-butanol or 1,4-butandiol, and it's linear so 2-propanol and 1,2-propanediol seem unlikely.
