Catalyzes the transfer of glucose from uridine diphosphoglucose to 5-hydroxymethyl cytosine of T4 DNA to yield glucosyl 5-hydroxymethyl cytosine (glc-HMC) . This DNA process seems to occur immediately after DNA synthesis since the DNA alpha-glucosyltransferase interacts with the clamp protein gp45. The glc-HMC modification protects the phage genome against its own nucleases and the host restriction endonuclease system. The glc-HMC modification also protects against the host CRISPR-Cas9 defense system.

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.

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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

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°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
