  • Nucleosomes tightly wrap ~147 DNA base pairs around an octamer of histone proteins, but how nucleosome structural dynamics affect genome functioning is not completely clear. Here authors employ all-atom molecular dynamics simulations of nucleosome core particles and observe that octamer dynamics and plasticity enable DNA unwrapping and sliding.

  • Nucleocytoplasmic Large DNA Viruses (NCLDV) that infect algae encode two distinct families of microbial rhodopsins. Here, the authors characterise two proteins form the viral rhodopsin group 1 OLPVR1 and VirChR1, present the 1.4 Å crystal structure of OLPVR1 and show that viral rhodopsins 1 are light-gated cation channels.
