摘要:
A novel restriction endonuclease and methods of making the same are obtainable from either Citrobacter species 2144 (NEB#1398) or the recombinant stain Escherichia coli (NEB#1554) which cleaves at nt sequence 5′-CAANNNNNGTGG-3′ (SEQ ID NO:14) in double-stranded DNA molecules. The novel restriction endonuclease is a modular protein in which the specificity moiety is an independent module from the restriction-modification module.

摘要:
Compositions for an alkaline phosphatase and methods for over-expression and purification of thermolabile Antarctic phosphatase (TAP) are provided. Uses for TAP include dephosphorylation of nucleic acids, sugars, peptides and proteins. TAP as described herein has advantages over phosphatases from other sources with respect to thermolability at 65° C. and efficiency of dephosphorylation activity at approximately neutral pH.
摘要:
The present invention relates to recombinant DNA that encodes the BseRI restriction endonuclease as well as M.BseRI, expression of BseRI restriction endonuclease and M.BseRI in E. coli cells containing the recombinant DNA.
