Some of the magnesium ions in ribosome are coordinated by multiple rRNA phosphate groups. These link distal sequences rRNA, primarily incorporating groups into first coordination shell. Less frequently, interacts with ribosomal proteins. Ribosomal protein L2 appears to be unique forming specific magnesium-mediated interactions rRNA. Using optimized models derived from X-ray structures, we subjected rRNA/magnesium/water/rProtein assemblies quantum mechanical analysis using density functional...

Studying the evolutionary history of life’s molecules - DNA, RNA, and protein reveals nature-based solutions to real-world problems. We discuss an approach applied molecular evolution that is well-known within field but may be unfamiliar a wider audience. Using case study at intersection medicine, we introduce fundamental concepts orthology paralogy . also explain practical entry point named STORI: Selectable Taxon Ortholog Retrieval Iteratively. STORI machine learning algorithm designed...

Abstract Seeking to reconstruct the biogeochemical processes that produced organic sulfur compounds in two unique depositional environments, we used nickel boride desulfurization reaction release hydrocarbons from sulfur-bound macromolecules not otherwise amenable chromatographic analysis. We desulfurized geochemical extracts: one sample is a Monterey shale of late Miocene age, and other surface sediment Greenland lake Brayasø. Both samples contained compounds, but was biologically thermally...
