[gmx-users] Alinging beta sheets

[Gaurav Porwal]

Hi,

>From a secondary structure prediction program, I'm able to get the
regions in the sequence where helices and beta strands are probably
present. As helices are independent structures, the whole region can be
specified as an helix and can be freezed during energy minimization.

The problem arrives in case of beta strands as two strands have to come
close in parallel/antiparallel fashion in order to form a sheet.

Is is possible to construct H bonds in GROMACS such that we can specify
which residues should be forming the bonds, so that two strands can be
forced to come close to form a sheet? In this way, beta sheets can
also be obtained which can later be freezed during energy minimization.

Kindly reply.

Thanks.

Regards,
Gaurav
