Summary: Phage portal protein, lambda family
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.
Phage portal protein, lambda family Provide feedback
This protein forms a hole, or portal, that enables DNA passage during packaging and ejection. It also forms the junction between the phage capsid and the tail proteins.

InterPro entry IPR006429
This entry is represented by Bacteriophage lambda, GpB, portal protein. The characteristics of the protein distribution suggest prophage matches in addition to the phage matches.
This group of sequences represent one of several distantly related families of phage portal protein. This protein forms a hole, or portal, that enables DNA passage during packaging and ejection. It also forms the junction between the phage head (capsid) and the tail proteins. It functions as a dodecamer of a single polypeptide of average mol. wt. of 40-90 kDa.

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
