The thiamine pyrophosphate (TPP) riboswitch is a cis-regulatory element in mRNA that modifies gene expression in response to TPP concentration. Its specificity is dependent upon conformational changes that take place within its aptamer domain. Here,

Kinesin-1 is a dimeric motor that transports cargo along microtubules, taking 8.2-nm steps in a hand-over-hand fashion. The ATP hydrolysis cycles of its two heads are maintained out of phase by a series of gating mechanisms, which lead to processive

RNA sequence-structure-function relationships can be studied via assays of variant activity. The authors developed a method to systematically determine ribozyme variant kinetics, using it to map double-mutant interactions and show that cleavage rate

Contacts between RNA polymerase and promoter DNA modulate the strength of binding and the frequency of promoter escape during transcription. Here, the authors describe a single molecule optical-trapping assay to study transcription initiation and obs

Massively parallel, quantitative measurements of biomolecular activity across sequence space can greatly expand our understanding of RNA sequence-function relationships. We report the development of an RNA-array assay to perform such measurements and

Significance Riboswitches are structured mRNA elements that regulate gene expression in response to metabolite ligands. The bacterial glmS riboswitch regulates a protein with a key role in cell wall biosynthesis. This riboswitch follows an unusual me

Riboswitches modulate gene expression in response to small-molecule ligands. Switching is generally thought to occur via the stabilization of a specific RNA structure conferred by binding the cognate ligand. However, it is unclear whether any such st

Increasing rates of burnout—with accompanying stress and lack of engagement—among faculty, residents, students, and practicing physicians have caused alarm in academic medicine. Central to the debate among academic medicine’s stakeholders are o

Eg5, a mitotic kinesin, has been a target for anticancer drug development. Clinical trials of small-molecule inhibitors of Eg5 have been stymied by the development of resistance, attributable to mitotic rescue by a different endogenous kinesin, KIF15
