Highly likely peptide flips
Checks if peptide flips of any type are needed
For the residues listed in the table below, the backbone formed by the
residue mentioned and the one N-terminal of it show strong systematic deviations
from normality that are highly consistent with a peptide flip.
This can either
be a 180 degree flip of the entire peptide plane or a trans to cis flip.
(Cis to trans flips cannot be detected yet). P(flip) is the likelihood
of the flip.
The type can be TT+, TC-, or TC+.
TT+ indicates a 180 degree flip of the entire peptide plane.
TC- indicates a trans to cis conversion that requires a flip of the N atom.
TC+ indicates a trans to cis conversion that requires a flip of the O atom.
This check return only the flips that WHAT IF is very, very certain about. The
next option also lists less likely peptide flips.
See our validation related
for more background details regarding the validation servers. See also the WWW based validation
explains how this specific peptide flip option works.
