Doping with Martini

A nice example of how Martini can help you improving your performance, featuring the first Martini 3.0 dope:

Lipidated aminoacids

Adding a lipid to your protein will be a piece of cake from now on.

Sticky proteins

Current force fields tend to overstabilize protein-protein interactions, and Martini is no exception. A recent paper by the Vattulainen group shows the stickiness is also haunting membrane embedded proteins:

We are working hard to improve the protein-protein interactions in the forthcoming Martini 3.0 force field, featuring a thoroughly recalibrated interaction matrix, with a planned release early 2018.
