Dear friends,

I came across one reference which describe N15 NNH separated NOESY experiment but I am not able to get more information about this experiment from other sources. Is this experiment useful for providing restraints for protein structure calculation. what kind of information this experiment can provide and how to set up. If anyone has references to suggest, please suggest.

Thanks & Regards

Hi Arun,

They might be referring to an HSQC-NOE-HSQC (or HMQC-NOE-HMQC, as originally described by Ikura et al JACS 112, 9020 (1990)). It's useful for identifying amide-amide NOEs when their proton chemical shifts are too close together. I think most people run it in its HSQC-NOE-HSQC form these days, or, for larger proteins as a 1H15N TROSY-NOE-TROSY. - Mark
