At 2%, acetate reached the active site at an RDF peak distance of 5.45 Å with g(r)=16.00; earlier experiments reported 50% activity retained, and the authors interpret the simulation as competitive inhibition. At 10%, TtL–acetate hydrogen bonds were 49.44 ± 7.81 versus 15.87 ± 5.11 at 2%; earlier experiments reported 10% activity retained, and the authors interpret the simulation as surface-associated noncompetitive inhibition.

Longer heparin chains strengthened simulated SARS-CoV-2 RBD binding in DNA-origami nanocomplexes: ΔGbind shifted from −36.9 to −170.9 kJ/mol and rupture force from ~350 to ~750 pN. 🎧 open.spotify.com/episode/4ID8... #JBSD

Six 200-ns simulations show how Aβ25–35 β-barrels disrupt POPC/POPG membranes: shallow barrels detach within 8–10 ns, deeper barrels remain embedded, and local effects reach ~1 nm while global thickness stays stable. 🎧 open.spotify.com/episode/6XZT... #MolecularDynamics

Using protein dynamics in RFdiffusion raised stable KRAS binder designs from 30% to 60%. Even the lowest-ranked dynamic design had a 42% larger buried interface and 57% more H-bonds than the best static design. New JBSD Audio Overview: open.spotify.com/episode/1JTM...

How can glycation weaken ApoE3’s lipid and heparin binding? In 1-µs simulations, MGH1 modifications opened the NT–CT interface; AP217 reached a 42.8 Å energy-minimum gap versus 13.3 Å native. New JBSD Audio Overview: open.spotify.com/episode/11Ns...
Scientific infographic titled How MGH1 Glycation Reshapes ApoE3, comparing the HelixC1-lock distance, final energy-minimum domain-gap distances for native and glycated ApoE3 systems, and structural changes affecting lipid and heparin binding.
