Expanding the set of residues that can match a single position in the input motif.

When the position Ser214 in the input motif (Ser195, His57, Ser214) can be matched by a Ser or Tyr, Tyr36 has a much better spatial orientation with respect to Ser49 and His48 as compared to Ser120 in the P14A protein (PDBid:1CFE). The distances are specified in the reference protein (PDBid:1B0F) in A. For the remaining, we show the deviation from the reference value. Potential differences are in units of kT/e (k is Boltzmann’s constant, T is the temperature in K and e is the charge of an electron). They are absolute values and not shown as deviations.
