Major capsid protein 10A

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 minor capsid protein 10B, 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

Interactioni

Subunit structurei

Interacts with connector protein gp8 and capsid protein 10B (PubMed:20962334, PubMed:23580619). Interacts with the capsid assembly scaffolding protein; capsid proteins and scaffolding proteins form building blocks that assemble to form the procapsid (PubMed:25313071).3 Publications

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.
