Phoebe, I'm red green blind myself, and it is not as straight forward as it sounds. The problem is that we "see" red and green despite lacking one of the color receptors (I actually prepared a figure using red and green once and got a referee comment that red/green blind people would have difficu

Professor Rice, When publishing in NAR (Nucleic Acids Research), it was recommended that we use "colors friendly to the color blind". You can read about it here: http://jfly.iam.u-tokyo.ac.jp/html/color_blind/ It is quite nice that they went to the trouble of showing us "how they see it". And

Why not use yellow carbons (colour by atom menu) and hit the builder button in pymol which shows bond order (carbonyls). You could also type colour gray, name o, this colours the carbonyls gray (or any other colour that works) "name o* colours all oxygens Hope this helps From: CCP4 bulletin boa

In our case, the Ca ion is essential for activity but not correct folding. The enzyme requires Ca2+ (Mg or Mn) for activity. The crystal structure shows a single Ca2+ ion coordinated by a key catalytic aspartate and two backbone carbonyls. Mutagenesis of the key Asparate abolishes enzyme activit

I would think a Google search would make some suggestions for you. There are lots of cases of proteins which require Calcium to function, but it is a bit chicken-and-egg-y - can the protein only function after it folds correctly, and is the Ca essential for that folding? On 31 May 2013 11:54, R
