    Mechanisms of opening and closing of the bacterial replicative helicase

    Jillian Chase et al.
    Analysis of the Escherichia coli DnaB helicase•bacteriophage λ helicase loader (λP) complex provides insights into helicase opening, delivery to the origin and ssDNA entry, and closing in preparation for translocation.

    Hexameric helicase G40P unwinds DNA in single base pair steps

    Michael Schlierf et al.
    Single-molecule FRET experiments reveal that G40P, a DnaB-like helicase, unwinds double-stranded DNA in single base pair steps and its processivity is enhanced by host primase DnaG.

    Reprogramming the antigen specificity of B cells using genome-editing technologies

    James E Voss et al.
    Antibody paratopes can be added to the human repertoire by CRISPR-Cas9 editing of B lymphocytes using a strategy that allows for hypermutation and class switching of resulting B cell receptors.

    Cis-regulatory evolution integrated the Bric-à-brac transcription factors into a novel fruit fly gene regulatory network

    Maxwell J Roeske et al.
    The conserved biochemical activity of the duplicate Bab transcription factors were integrated into the regulatory hierarchy of an evolving gene regulatory network by binding site gains in a target gene's cis-regulatory region.

    Frequent exchange of the DNA polymerase during bacterial chromosome replication

    Thomas R Beattie et al.
    DnaB Helicase is the only stable component of the bacterial replisome as the replicative DNA polymerase frequently exchanges in both leading and lagging strands.

    Role of framework mutations and antibody flexibility in the evolution of broadly neutralizing antibodies

    Victor Ovchinnikov et al.
    Computer simulations of the evolution of broadly neutralizing antibodies against HIV suggest that non-traditional pathways involving framework mutations which lead initially to increased antibody flexibility do occur, but can be avoided by appropriate vaccine design.

    A deleterious gene-by-environment interaction imposed by calcium channel blockers in Marfan syndrome

    Jefferson J Doyle et al.
    Calcium channel blockers accelerate aortic aneurysm and cause premature aortic rupture in a mouse model of Marfan syndrome through protein kinase C-mediated activation of extracellular signal-regulated kinase.
