CG vesicle

Description

This is an example of a mixture of different coarse-grained biomolecule models (published in different papers), mixed together using MOLTEMPLATE and PACKMOL to build a large coarse-grained vesicle. Some minor adjustments to the force-field were necessary after mixing the three types of coarse-grained molecules together. (Further adjustment may be necessary for realistic results. See "CGLipidBr2005.lt" , "1beadProtSci2010.lt" , and "system.lt" for details.)
The DPPC lipid model is described here: G. Brannigan, P.F. Philips, and F.L.H. Brown, Physical Review E, Vol 72, 011915 (2005) (The DLPC model is a truncated version of DPPC.)
The protein model is described here: G. Bellesia, AI Jewett, and J-E Shea, Protein Science, Vol19 141-154 (2010)
