Minor capsid protein 10B

Gene

10

Organism
Enterobacteria phage T7 (Bacteriophage T7)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Assembles, with major capsid protein 10A, to form an icosahedral capsid with a T=7 symmetry, about 60 nm in diameter, and consisting of 415 capsid proteins (PubMed:20962334). The major and minor capsid proteins are incorporated into the capsid in about a 90/10 ratio respectively. Once the capsid formed, encapsidates one single copy of the T7 genome.1 Publication

Miscellaneous

The minor capsid protein 10B is due to a translational shift to the -1 frame of the major capsid protein mRNA 10A.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
