Source: E.coli

Tag Info: N-terminal 6xHis-SUMO-tagged

Expression Region: 1-319aa

Sequence Info: Full Length

MW: 51.7 kDa

Purity: Greater than 90% as determined by SDS-PAGE.

Relevance: This methylase recognizes the double-stranded sequence GAATTC, causes specific methylation on A-? on both strands, and protects the DNA from cleavage by the RsrI endonuclease.

Reference: Purification, cloning and sequence analysis of RsrI DNA methyltransferase lack of homology between two enzymes, RsrI and EcoRI, that methylate the same nucleotide in identical recognition sequences.Kaszubska W., Aiken C., O'Connor D., Gumport R.I., Stephenson F.H., Greene P.J.Nucleic Acids Res. 17:10403-10425(1989)

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20?/-80?. The shelf life of lyophilized form is 12 months at -20?/-80?.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4? for up to one week.

Function: This methylase recognizes the double-stranded sequence GAATTC, causes specific methylation on A-? on both strands, and protects the DNA from cleavage by the RsrI endonuclease.

Paythway:

Form: Liquid or Lyophilized powder

Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20?/-80?. Our default final concentration of glycerol is 50%. Customers could use it as reference.
