Dear Amber Users,
Now I am trying to put the "Leu-NH & Hb" distance restraints in the MD calcuations. Hb includes 2 H atoms. Here is the atoms that I want to add the restraints:
resid 1-5: H118 with resid 1-5: H140, H141 2.00 5.00
resid 1-5: H79 wtih resid 1-5: H101, H102 2.00 5.00
resid 1-5: H40 with resid 1-5: H62, H63 2.00 5.00
resid 1-5: H with resid 1-5: H22, H23 2.00 5.00
I need to specify the restraints between H118 and H140, H141 intra-residue, then average these 5 residues results.
Here is the DISANG file:
# Leu-NH & Hb
&rst iat=-1,-1, iresid=1,
r1= 1.50, r2= 2.00, r3= 5.00, r4= 5.50,
rk2=20.0, rk3=20.0, ir6=1, ialtd=0,
igr1 =1,2,3,4,5, grnam1(1) = 'H118',
igr2 =1,1,2,2,3,3,4,4,5,5, grnam2(1)= 'H140', grnam2(2)='H141',
/
&rst iat=-1,-1, iresid=1,
r1= 1.50, r2= 2.00, r3= 5.00, r4= 5.50,
rk2=20.0, rk3=20.0, ir6=1, ialtd=0,
igr1 =1,2,3,4,5, grnam1(1) = 'H79',
igr2 =1,1,2,2,3,3,4,4,5,5, grnam2(1)= 'H101', grnam2(2)='H102',
/
&rst iat=-1,-1, iresid=1,
r1= 1.50, r2= 2.00, r3= 5.00, r4= 5.50,
rk2=20.0, rk3=20.0, ir6=1, ialtd=0,
igr1 =1,2,3,4,5, grnam1(1) = 'H40',
igr2 =1,1,2,2,3,3,4,4,5,5, grnam2(1)= 'H62', grnam2(2)='H63',
/
&rst iat=-1,-1, iresid=1,
r1= 1.50, r2= 2.00, r3= 5.00, r4= 5.50,
rk2=20.0, rk3=20.0, ir6=1, ialtd=0,
igr1 =1,2,3,4,5, grnam1(1) = 'H',
igr2 =1,1,2,2,3,3,4,4,5,5, grnam2(1)= 'H22', grnam2(2)='H23',
/
Do you think it is correct to realize what I want for the restraints? Thanks a lot for your any suggestion and help!
All the bests,
Esther B.
