    摘要: Some aspects of the present disclosure provide methods for evolving recombinases to recognize target sequences that differ from the canonical recognition sequences. Some aspects of this disclosure provide evolved recombinases, e.g., recombinases that bind and recombine naturally-occurring target sequences, such as, e.g., target sequences within the human Rosa26 locus. Methods for using such recombinases for genetically engineering nucleic acid molecules in vitro and in vivo are also provided. Some aspects of this disclosure also provide libraries and screening methods for assessing the target site preferences of recombinases, as well as methods for selecting recombinases that bind and recombine a non- canonical target sequence with high specificity.

    摘要: Hyperactive Hermes Transposase mutants and genes encoding them are disclosed. These transposases are easily purified in large quantity after expression in bacteria. The modified Hermes Transposases are soluble and stable and exist as smaller active complexes compared to the native enzyme. The consensus target DNA recognition sequence is the same as the native enzyme and shows minimal insertional sequence bias. These properties are useful in whole genome sequencing applications that involve sample DNA preparation requiring simultaneous fragmentation and attachment of custom sequences to the ends of the fragments. Methods and compositions using these transposases in fragmentation and 5' end-tagging are also disclosed.
