Martini 2.3 featuring cation-π interactions

Check out this improved version of Martini, now able to represent cation-π interactions and allowing a much more realistic binding of peripheral membrane proteins. The version is coined 2.3, but should not be confused with the forthcoming release of Martini 3 which concerns a thorough recalibration of the full interaction matrix. For details, see:

H.M. Khan et al., Capturing choline-aromatics cation-π interactions in the MARTINI force field, JCTC, 2020.

The new parameter definitions can be downloaded here.

Martini twitter account

Apparently there is this new platform called 'twitter'. I thought it would be a good idea to open an account for Martini, so interested people can keep up to date with the latest developments. Check @CG_Martini and #CG_Martini and spread the word ....

Martini proteins on the move

The application range of Martini keeps expanding. See for instance this recent publication from a Japanese group on conformational changes of a protein upon ligand binding:

Honorary doctorate

DOCTOR-HONORIS-CAUSA.jpg Largely based on the success story of Martini, the University Polytechnica of Bucharest has awarded Prof. Marrink a honorary doctorate ("honoris causa").

See here for more details of the ceremony, which took place on January 15th in Bucharest in the presence of the rector and several local professors, as well as the embassador of the Netherlands in Romenia.

Stress, stress, nothing but stress ....

Do you find working with lipid membranes stressful ? No wonder ! Check out this new paper from the Deserno group, and learn about how difficult it is to get rid of stress in membranes ....

Lipid shape and tuberculosis

The team of Matthieu Chavent has elucidated the role of a specific class of lipids, phthiocerol dimycocerosate (DIM), in phagocytosis of macrophages such as mycobacterium tuberculosis. Read all about it in: Augenstreich et al., The conical shape of DIM lipids promotes Mycobacterium tuberculosis infection of macrophages, PNAS 2019, in press.
