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?

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
