Purple phototrophic bacteria produce two kinds of light-harvesting complexes that function to capture and transmit solar energy: the core antenna (LH1) and the peripheral antenna (LH2). The apoproteins of these antennas, encoded respectively by the genes pufBA and pucBA within and outside the photosynthetic gene cluster, respectively, exhibit conserved amino acid sequences and structural topologies suggesting they were derived from a shared ancestor. Here we present the structures of two photosynthetic complexes from Roseospirillum (Rss.

Unlabelled: The nickel-pincer nucleotide (NPN) cofactor is a modified pyridinium mononucleotide that tri-coordinates nickel and is crucial for the activity of certain racemases and epimerases. LarB, LarC, and LarE are responsible for NPN synthesis, with the cofactor subsequently installed into LarA homologs. Hurdles for investigating the functional properties of such proteins arise from the difficulty of obtaining the active, NPN cofactor-loaded enzymes and in assaying their diverse reactivities.

Our study seeks to provide a theoretical foundation for the clinical use of cold-stored platelets (CSPs) by interpreting ultrastructural images and quantitatively analyzing structural changes. CSPs, room temperature-stored platelets (RTPs), and delayed CSPs (delayed-CSPs) were continuously observed using scanning electron microscopy and transmission electron microscopy at eight time points. Super-resolution fluorescence microscopy was employed to observe changes in platelet microtubules and mitochondrial structure and function, whereas platelet counts, metabolism, and relevant functional indicators were measured concurrently.
