    “…Then we show how the backward translocation motions are prevented at post-translocation upon successful nucleotide incorporation, which is also subject to stepwise nucleotide selection and acts as a pawl for “selective ratcheting”. The structural dynamics and energetics features revealed from our atomistic molecular dynamics (MD) simulations and related analyses on the single-subunit T7 RNAP thus provided detailed and quantitative characterizations on the Brownian-ratchet working scenario of a prototypical transcription machine with sophisticated nucleotide selectivity for fidelity control. …”

    “…The model demonstrates how the decoding centre releases a codon–anticodon duplex, allowing its movement on the ribosome, and emphasizes the function of eEF2 as a ‘pawl’ defining the directionality of translocation(3). …”

    “…Introduction: The ζ subunit is a potent inhibitor of the F(1)F(O)-ATPase of Paracoccus denitrificans (PdF(1)F(O)-ATPase) and related α-proteobacteria different from the other two canonical inhibitors of bacterial (ε) and mitochondrial (IF(1)) F(1)F(O)-ATPases. ζ mimics mitochondrial IF(1) in its inhibitory N-terminus, blocking the PdF(1)F(O)-ATPase activity as a unidirectional pawl-ratchet and allowing the PdF(1)F(O)-ATP synthase turnover. ζ is essential for the respiratory growth of P. denitrificans, as we showed by a Δζ knockout. …”
