Selection of bacteriophage lambda integrases with altered recombination specificity by in vitro compartmentalization.

abstract：:Bacterial RNase III plays important roles in the processing and degradation of RNA transcripts. A major goal is to identify the cleavage targets of this endoribonuclease at a transcriptome-wide scale and delineate its in vivo cleavage rules. Here we applied to Escherichia coli grown to either exponential or stationary...
