UniProtKB - O64329 (GT_BPN15)
Protein
Tail assembly protein GT
Gene
gene 15
Organism
Escherichia phage N15 (Bacteriophage N15)
Status
Functioni
Promotes tail assembly by creating a scaffold for the tail tube proteins. Tail assembly proteins G and GT probably wrap the linear tape measure protein to create a tail assembly scaffold. This allows the polymerization of the tail tube protein, during which G and GT are released, therefore they are absent in the mature virion. The tail assembly protein GT is produced by a rare -1 ribosomal frameshift. The ratio of translated G/GT is about 20, and this ratio is important for proper tail assembly.UniRule annotation
