Hi all- I recall seeing a long time ago a figure which showed the progressive improvement of electron density as one increases resolution, say from 6 to 3.5 to 2A. I believe I've seen two versions- one a larger scale pic showing the ability to model side chains of alpha helices at higher resolutions and the other a simpler graphic of a tyrosine aromatic ring showing the electron density hole in the middle of the ring once near atomic resolution maps are obtained. Does anyone have, in their teaching notes or a textbook or presentation, a graphic which displays this? I need it for a talk this weekend and Google searches have come up blank. If all else fails, I can generate it myself...(lazy sigh)
Thanks in advance- Brad
