    A reverse transcriptase ribozyme

    Biswajit Samanta, Gerald F Joyce
    An RNA enzyme is shown to function as a reverse transcriptase, an activity thought to be crucial for the transition from RNA to DNA genomes during the early history of life on Earth.

    Asymmetric conformational maturation of HIV-1 reverse transcriptase

    Xunhai Zheng et al.
    HIV-1 reverse transcriptase uses a metamorphic polymerase domain that minimizes its coding requirements but requires a complex maturation process.

    Single-molecule imaging of telomerase reverse transcriptase in human telomerase holoenzyme and minimal RNP complexes

    Robert Alexander Wu et al.
    New labeling approaches for single-molecule fluorescence microscopy detect the monomeric catalytic subunit of human telomerase within cellular holoenzyme and minimal active recombinant enzyme.

    Structural basis for potent and broad inhibition of HIV-1 RT by thiophene[3,2-d]pyrimidine non-nucleoside inhibitors

    Yang Yang et al.
    High-resolution structures of HIV-1 RT in complex with two newly developed non-nucleoside inhibitors explain how they retain antiviral activities against drug-resistant RT mutants with considerably reduced susceptibility to rilpivirine.
  1. Point of view: Motivating participation in open science by examining researcher incentives

    Sarah E Ali-Khan et al.
    A survey of researchers at the Montreal Neurological Institute and Hospital provides insights into the challenges and opportunities involved in adopting an open science policy across an entire patient-oriented academic institution.
