Piia Bartos<p>We recently published a study where we compared a few common force fields and their usability with RNA-protein complexes.</p><p>Shortly: All the force fields (ff14SB/ff19SB+OL3, OPLS4, AMOEBA) produce okay simulations. Polarization (AMOEBA force field or O3P water) might cause structural instability if protein has longer loops. </p><p><a href="https://mstdn.science/tags/compchem" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>compchem</span></a> <a href="https://mstdn.science/tags/RNA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RNA</span></a> <a href="https://mstdn.science/tags/protein" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>protein</span></a> <a href="https://mstdn.science/tags/forcefield" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>forcefield</span></a> <a href="https://mstdn.science/tags/simulation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>simulation</span></a> <a href="https://mstdn.science/tags/publication" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>publication</span></a> </p><p><a href="https://www.frontiersin.org/articles/10.3389/fchem.2023.1217506/full" rel="nofollow noopener noreferrer" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">frontiersin.org/articles/10.33</span><span class="invisible">89/fchem.2023.1217506/full</span></a></p>
