Dear Amber users,
I want to simulate the dynamics of an *intrinsically disordered *peptide (40
aa) at 298 K and 1 bar, with ff9SB-ILDN or ff99SBnmr1. I have 13CO, 13Ca,
and 13Cb NMR chemical shift values for a homologous peptide (82% sequence
identity, 90% sequence similarity) which all lie within the random coil
area. Do you reckon it is worth applying chemical shift restraints taken
from the homologue to my target peptide , or just leave the ff do its job
and then see if the calculated chemical shifts correlate with the
experimental? I would greatly appreciate any comments about this case.
thanks in advance,
Thomas
