Here is a little MD simulation of
the Glucose-6-phosphate dehydrogenase (pentose phosphate pathway) as homodimer from Leuconostoc mesenteroides in a physiological environment 150mM NaCl using Gromacs with the amber99SB-ILDN force field (1ns - 9h, 8 cores).
Semester Wochenstundenlaner ( schedule of study courses ) written in Java.
Sorry, but the applet functionality does not match every feature used within this piece of code.
Thus, download and give it a try...
