Copper and the ACE1 regulatory protein reversibly induce yeast metallothionein gene transcription in a mouse extract.

abstract：:Accurate modification of the 3 billion-base-pair human genome requires tools with exceptional sequence specificity. Here, we describe a general strategy for the design of enzymes that target a single site within the genome. We generated chimeric zinc finger recombinases with cooperative DNA-binding and catalytic speci...
