    Radiative effect of thin cirrus clouds in the extratropical lowermost stratosphere and tropopause region by R. Spang, R. Müller, A. Rap

    Published 2024-01-01
    “…In addition, their short-wave (cooling) and long-wave (warming) radiative effects are often in approximate balance, and their net effect strongly depends on the shape and size of the cirrus particles. However, the CRyogenic Infrared Spectrometers and Telescopes for the Atmosphere instrument (CRISTA-2) allows ultra-thin cirrus clouds to be detected. …”

    Structural investigations of adenosylcobalamin-dependent enzyme maturation by Vaccaro, Francesca A.

    Published 2023
    “…We also present mutagenesis and solution state data for IcmF from C. metallidurans that characterize its nucleotide- and cofactor-state dependent oligomerization, important for cofactor loading and unloading. Using cryogenic electron microscopy, we obtain structural data on IcmF that show that the monomeric G-protein domains of IcmF dimerize to resemble the active conformation of dimeric MeaB, and that this “active” conformation of the G-protein domains physically props open the mutase domains to enable AdoCbl loading. …”
