Hi everyone, hope you are all fine
I wish I could be of more help in discussing the interesting ideas on
the structural data, both the NMR experiments and the MD simulations (by
the way, fantastic images Francisco!) but unfortunately my
biological/biomedical background is insufficent, and therefore I am
mostly expecting your specialized steering on this - sorry!
hope to obtain more protein and send it soon...
all the best
Bruno
