Protein attributes

Sequence length	351 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the transfer of glucose (Glc) from uridine diphosphoglucose (UDP-Glc) to 5-hydroxymethylcytosine (5-HMC) in double-stranded DNA. Is involved in a DNA modification process to protect the phage genome against its own nucleases and the host restriction endonuclease system.
Catalytic activity	Transfers a beta-D-glucosyl residue from UDP-glucose to an hydroxymethylcytosine residue in DNA.
Pathway	Genetic information processing; DNA modification.
Subunit structure	Monomer.
