摘要： The present invention provides engineered RNA polymerase variants and compositions comprising these variants. The present invention further provides engineered T7 RNA polymerase variants and compositions comprising these variants. These variants have been evolved for selective incorporation of the m7G(5′)ppp(5′)m7G cap analog over GTP at the initiation of in vitro transcription. The present invention also provides methods for selective capping of RNA transcripts.

摘要： Compositions, methods and kits are provided that include an inhibitory oligonucleotide RNase inhibitor capable of inhibiting one or more types of RNase that coexist with biological samples or are introduced in the laboratory, thereby protecting RNA in the sample from degradation. More than one type of oligonucleotide RNase inhibitor may be combined in a mixture to inhibit a plurality of different RNases. Single oligonucleotides were identified to have inhibitory activity for a plurality of different RNases. The RNase oligonucleotide inhibitor may be immobilized on beads or other surface. It may be stored in a lyophilized form or in solution.

摘要： Some aspects of this disclosure provide methods for phage-assisted continuous evolution (PACE) of proteases. Some aspects of this invention provide methods for evaluating and selecting protease inhibitors based on the likelihood of the emergence of resistant proteases as determined by the protease PACE methods provided herein. Some aspects of this disclosure provide strategies, methods, and reagents for protease PACE, including fusion proteins for translating a desired protease activity into a selective advantage for phage particles encoding a protease exhibiting such an activity and improved mutagenesis-promoting expression constructs. Evolved proteases that recognize target cleavage sites which differ from their canonical cleavage site are also provided herein.

摘要： The invention relates to methods for template-independent synthesis of nucleic acids, comprising iteratively contacting an initiator sequence comprising a 3′-end nucleotide with a free 3′-hydroxyl group, with at least one nucleoside triphosphate, or a combination of nucleoside triphosphates, in the presence of an archaeal DNA primase or a functionally active fragment and/or variant thereof, thereby covalently binding said nucleoside triphosphate to the free 3-hydroxyl group of the 3-end nucleotide. It also relates to isolated functionally active fragments of archaeal DNA primases which are capable of template-independent terminal nucleotidyl transferase activity but are devoid of a template-independent primase activity.
