    Lack of activity of recombinant HIF prolyl hydroxylases (PHDs) on reported non-HIF substrates

    Matthew E Cockman et al.
    Assays using recombinant HIF prolyl hydroxylases did not support hydroxylation of more than 20 reported non-HIF substrates under conditions where robust HIF hydroxylation was observed.

    Robust cullin-RING ligase function is established by a multiplicity of poly-ubiquitylation pathways

    Spencer Hill et al.
    Human cullin-RING ligases are buffered to a much greater extent than had been previously appreciated, and the roles of ubiquitin chain extension enzymes are far more nuanced at physiological concentrations.

    Genetic code expansion enables visualization of Salmonella type three secretion system components and secreted effectors

    Moirangthem Kiran Singh et al.
    Genetic code expansion (GCE) enables site-specific labeling and visualization of Salmonella secreted effectors, secretion system components and provides a viable alternative for labeling proteins that do not tolerate N- or C-terminal tags.

    Molecular basis for allosteric specificity regulation in class Ia ribonucleotide reductase from Escherichia coli

    Christina M Zimanyi et al.
    Substrate and effector bound structures of a bacterial ribonucleotide reductase reveal the molecular basis by which substrate preference is modulated by a distal site on the enzyme.

    Ancestral resurrection reveals evolutionary mechanisms of kinase plasticity

    Conor J Howard et al.
    Reconstructing ancestral enzymes has revealed that a switch in kinase substrate preference evolved via an expanded specificity intermediate that is tolerated in vivo, thus providing a path for kinase diversification.

    Molecular basis for substrate specificity of the Phactr1/PP1 phosphatase holoenzyme

    Roman O Fedoryshchak et al.
    Interaction of cofactor Phactr1 with PP1 creates a composite substrate-binding surface that defines the sequence specificity of the Phactr1/PP1 holoenzyme.

    An atomic-resolution view of neofunctionalization in the evolution of apicomplexan lactate dehydrogenases

    Jeffrey I Boucher et al.
    The convergent evolution of unusually strict substrate specificity in apicomplexan LDHs arose by classic neofunctionalization of a duplicated MDH gene via few mutations of large effect.

    Intrinsic sequence specificity of the Cas1 integrase directs new spacer acquisition

    Clare Rollie et al.
    The acquisition of new foreign DNA by the prokaryotic adaptive immune system CRISPR-Cas is shown to depend on the fundamental sequence specificity of the Cas1 integrase.

    Fine-tuning of substrate preferences of the Src-family kinase Lck revealed through a high-throughput specificity screen

    Neel H Shah et al.
    A high-throughput comparison of substrate specificities of the Src-family kinases Lck and c-Src against a library of proteome-derived phosphorylation sites reveals that Lck has evolved divergent electrostatic features reflecting its involvement in T-cell signaling.

    Identification of PNG kinase substrates uncovers interactions with the translational repressor TRAL in the oocyte-to-embryo transition

    Masatoshi Hara et al.
    The threonine kinase controls maternal mRNA translation phosphorylate components of the translational machinery, including translational repressors, which appear to inactivate to promote the oocyte-to-embryo transition.
