Structural insights into RNA-dependent ring closure and ATPase activation by the Rho termination factor
Article Abstract:
The structure of the Rho transcription termination factor, a hexameric RNA/DNA helicase, is determined with single-stranded RNA bound to the motor domains of the protein. The structure has described the molecular effects of numerous mutations and has provided new insights into the links between substrate recognition, ATP turnover and coordinated strand movement.

Activation of glucosidase via stress-induced polymerization rapidly increases active pools of abscisic acid
Article Abstract:
A study report about AtBG1, a [beta]-glucosidase, which hydrolyzes glucose-conjugated, biologically inactive abscisic acid (ABA) to produce active ABA, is presented. The report suggests that the activation of inactive ABA pools by polymerized AtBG1 is a mechanism by which plants rapidly adjust ABA levels and respond to changing environmental cues.
