Protein

Base plate structural protein gp8

Gene
8
Organism
Enterobacteria phage T4 (Bacteriophage T4)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

Functioni

Structural component of the baseplate. The baseplate is a multicomponent protein complex which controls phage attachment to the host. During infection, the baseplate undergoes a conformational change from a dome-shaped to a star-shaped structure.
