[ccp4bb] Please share your experience about "ugly" crystals showing good diffraction

2018-06-28 Thread Anirban Banerjee
Dear all, Apologies for the non-CCP4 related question. If you have concrete experience about visually unappealing, i.e. ugly crystals ( your own take on ugly is fine) diffracting better than comparably similar sized nicer looking crystals of the same protein, will you please share here ? Even be

Hi Anirban, At JCSG, we subjected ~180,000 crystals from ~3500 unique/novel proteins/complexes to X-ray diffraction screening, resulting in >1500 novel structures in the PDB at an average resolution ~2.0A. In theory, if we had the bandwidth now to sort through all that data to pull out images of t

Good evening, Over the years I've seen great diffraction from any number of hideous brittle plates with perforated edges, 'Krypton skyscrapers', curved whiskers, 'hypodermic needles', even from crystals that looked like cat vomit (hairballs), and so forth. The structure *ab ovo* story is my favor

: [ccp4bb] Please share your experience about "ugly" crystals showing good diffraction Hi All I have a comment, based on my old supervisor's explanation, which seemed to make sense. Crystals usually grow layer by layer. Once a new layer is formed it quickly expands to cover th
