No, it does NOT!

HAve you red the paper?!

This implementation is an adoc representation to mimic specific sequences of short peptides! They do never for any secondary structure!

Hi rama,
actually MARTINI has been further improved to allow secondary structure
change.
The title is:
*"Improving Internal Peptide Dynamics in the Coarse-Grained MARTINI Model:
Toward Large-Scale Simulations of Amyloid- and Elastin-like Peptides"*

and here there is a link to the paper:

Nope, but on other softwares.

Thank you for your reply,

Are these Cg can be used in Gromacs.

Thank you in advance.

With best wishes and regards,

Martini FF cannot model changes in secondary structure ... other CG FF can. You'll find them easily in the literature. Notably the ones from
Deserno or Derreumaux.

Hi friends,


I planed to use the martini force-field for my simulation study of
peptide.

The peptides are initially alpha-helix in nature. As they come together
they formed amyloid fibre( Antiparallel Beta structure).

Is it is possible to study the secondary structure backbone study by
martini force field.????

I read in there tutorial that the Secondary structure is predefined
therefore they are statics through out the simulation.
Conformational changes that produces changes in Sec structure are out
of
scope in martini. only tertiary structure are free defined to change..


So what to do ???
How to use Martini FF to study secondary structure ???

Is there any way to use coarse grained FF to use for study in Sec.
structure???


With Best wishes and regards,
Rama David
