    摘要: The present invention is directed to the discovery of a novel family of enzymes designated herein as mRNA interferases that exhibit endoribonuclease activity. The novel finding of the present inventors, therefore, presents new applications for which mRNA interferase nucleic and amino acid sequences, and compositions thereof may be used to advantage. The invention also encompasses screening methods to identify compounds/agents capable of modulating mRNA interferase activity and methods for using such compounds/agents. Also provided is a kit comprising mRNA interferase nucleic and/or amino acid sequences, mRNA interferase activity compatible buffers, and instruction materials.

    摘要: A regulated deployment of a toxin gene for developmental programmed cell death in bacteria is described. M. xanthus is demonstrated to have a solitary mazF gene that lacks a cotranscribed antitoxin gene. Deletion of mazF results in elimination of the obligatory cell death during development causing dramatic reduction in spore formation. Surprisingly, MrpC functions as a MazF antitoxin and a mazF transcription activator. Transcription of mrpC and mazF is negatively regulated via MrpC phosphorylation by a Ser/Thr kinase cascade. Various methods of exploiting this novel pathway are described herein.
