Summary: Superinfection immunity protein
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.
Superinfection immunity protein Provide feedback
This family includes the E. coli bacteriophage T4 superinfection immunity (imm) protein, P08986. When E. coli is sequentially infected with two T-even type bacteriophage the DNA of the superinfecting phage is excluded from the host, into the periplasmic space. The immunity protein plays a role in this process .

InterPro entry IPR016410
This entry contains proteins related to the phage/prophage-immunity proteins and includes the immunity (imm) gene of the Escherichia coli bacteriophage T4. The Imm protein affects the exclusion of phage superinfecting cells already infected with T4. Phage which were excluded upon infection of cells possessing a plasmid-encoded Imm protein ejected only about one-half of their DNA. Therefore, the Imm protein inhibited, directly or indirectly, DNA ejection [PUBMED:2746737].

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request
