#  (5) Sugar pucker restraints
#
#  Based on DQFCOSY H1'-H2' cross-peaks,
#  residues U9, U10, C11, C12, U13, and G27 were restrained to
#  C2'-endo sugar pucker; the rest of residues were restrained
#  to C3'-endo sugar pucker.
#
#  The following restrints were used for the C3'-endo sugar pucker
#  (using AMBER flat-well potential):
#  C5'-C4'-C3'-O3' = 79 to 95 deg. (delta backbone torsion angle)
#  C3'-C2'-C1'-O4' = -30 to -18 deg. (endocyclic torsion angle)
#  C4'-C3'-C2'-C1' = 35 to 39 deg. (endocyclic torsion angle)
#
#  The following restrints were used for the C2'-endo sugar pucker
#  (using AMBER flat-well potential):
#  C5'-C4'-C3'-O3' = 120 to 160 deg. (delta backbone torsion angle)
#  C3'-C2'-C1'-O4' = 34 to 37 deg. (endocyclic torsion angle)
#  C4'-C3'-C2'-C1' = -37 to -19 deg. (endocyclic torsion angle)
