The large atom of the end of the modification looks wrong to me for BME. If it were BME it would just be an oxygen right? ________________________________________ From: CCP4 bulletin board [[email protected]] On Behalf Of RHYS GRINTER [[email protected]] Sent: 14 January 2015 00:48 To: [email protected] Subject: [ccp4bb] Post-translational modification of cystine
Hi All, I think everyone enjoys this game, so to save me a trawl through the literature can anyone help me interpret this density? The density on the end extents to 7.4 sigma, so something reasonably large. I guess it's some kind of PTM of the cystine residues, but nothing specific springs to mind. the crystallization conditions were 0.1 M CITRIC ACID, PH 5.0, 2.0 M NACL. Cheers, Rhys
