hi all
I have made a dipeptide in xleap (phe-dehydrophenylalanine) using the command
dipeptide=sequence {NPHE CPHE}
since dehydrophenylalanine is a non standard residue so i editted it
manually in xleap. i added a double bond between alpha carbon and beta
carbon and did necessary changes., now i need to set the angle between
alpha carbon and beta carbon to 0 degrees. when i look at frcmod file
which could be loaded in xleap to make necessary changes, i do not
understand its format.what is PN number there?
also i need to make two structures each with
PSI= PHI=180 and chi =0
and the other is PSI=PHI=-180 and chi=0
please help me with this as i am making mistakes and thus not able to
generate the required structure.
thanx
