    Insight into the evolution of microbial metabolism from the deep-branching bacterium, Thermovibrio ammonificans

    Donato Giovannelli et al.
    The genome of Thermovibrio ammonificans encodes ancestral pathways (e.g., hydrogen oxidation) and more recently acquired ones (e.g., nitrate reduction) and a hybrid pathway for CO2 fixation.

    Mechanism of chiral proofreading during translation of the genetic code

    Sadeem Ahmad et al.
    Structural biology has elucidated the mechanism of a configuration-specific enzyme that decouples D-amino acids from the translational machinery and, therefore, is involved in the enforcement of homochirality during protein synthesis.

    NusG inhibits RNA polymerase backtracking by stabilizing the minimal transcription bubble

    Matti Turtola, Georgiy A Belogurov
    NusG enhances transcription elongation by stabilizing DNA base pairs immediately upstream of the RNA-DNA hybrid but does not measurably affect the nucleotide incorporation and the forward translocation by RNA polymerase.
