Relaxed peptide flips


Introduction

Checks if peptide flips of any type are needed

Methods

For the residues listed in the table below, the backbone formed by the residue mentioned and the one N-terminal of it show systematic deviations from normality that are 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 option returns all putative peptide flips, the previous option in this list lists only those that WHAT IF is realy very certain about.
Either Choose a pdb-file,
Or Choose your own file

See our validation related articles for more background details regarding the validation servers. See also the WWW based validation explanation. explains how this specific peptide flip option works. If you have detected any error, or have any question or suggestion, please send an Email to Gert Vriend.
