The novel cryo-electron microscopy structure of a bacterial protein-only RNase P illustrates how a small protein oligomerizes into a dodecameric assembly to catalyze the 5’-end maturation of tRNAs.

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.
A phage-encoded protein inhibits a bacterial replicative helicase loading factor by exploiting an internal site that auto-regulates loader self-assembly and ATPase activity.
Par3 is polarized in the plane of the vertebrate neural plate, binds and recruits Prickle3 to the apical membrane and promotes the formation of core planar cell polarity complexes.
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.
