==About this Structure==
</table>
[[1jnb]] is a 12 chain structure with sequence from [http://en.wikipedia.org/wiki/Bacillus_phage_phi29 Bacillus phage phi29]. Full crystallographic information is available from [http://oca.weizmann.ac.il/oca-bin/ocashort?id=1JNB OCA].  
== Function ==
 
[https://www.uniprot.org/uniprot/PORTL_BPPH2 PORTL_BPPH2] Forms the portal vertex of the capsid (PubMed:10801350) (PubMed:19744688, PubMed:21570409). This portal plays critical roles in head assembly, genome packaging, neck/tail attachment, and genome ejection (By similarity). The portal protein multimerizes as a single ring-shaped homododecamer arranged around a central channel (PubMed:11812138, PubMed:21570409). Binds to the 6 packaging RNA molecules (pRNA) forming a double-ring structure which in turn binds to the ATPase gp16 hexamer, forming the active DNA-translocating motor (PubMed:15886394, PubMed:11130079). This complex is essential for the specificity of packaging from the left DNA end.[UniProtKB:P13334]<ref>PMID:11130079</ref> <ref>PMID:11812138</ref> <ref>PMID:15886394</ref> <ref>PMID:19744688</ref> <ref>PMID:21570409</ref> <ref>PMID:10801350</ref>
