== Function ==
 +
[[http://www.uniprot.org/uniprot/V03_BPT7 V03_BPT7]] Prevents both degradation and modification of T7 DNA by the host restriction-modification complex. Structural mimic of the phosphate backbone of B-form DNA that binds to and completely occupies the DNA-binding site of all type I restriction/modification enzymes. Thereby, inhibits the restriction endonuclease activity and protects the phage genome as it penetrates into host cytoplasm.<ref>PMID:1095770</ref> <ref>PMID:12235377</ref>
