Baseplate tail-tube junction protein gp48

Gene

48

Organism
Enterobacteria phage T4 (Bacteriophage T4)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Baseplate protein that forms, together with gp54, the baseplate-tail tube junction. The tail tube first 2 annuli are formed by gp48 and gp54, which are in continuation of the spike complex. Involved in the tail assembly. Morphogenesis of the baseplate is completed by association of gp48 and gp54, which bind the upper part of the baseplate dome to form the platform for polymerization of the tail tube.1 Publication2 Publications

Interactioni

Subunit structurei

Homohexamer (PubMed:27193680). The tube first annulus is composed of a gp48 hexameric ring. Interacts with gp54. Part of the baseplate macromolecular complex which consists of gp5, gp5.4, gp27 (central spike complex); gp6, gp25, gp53 (inner baseplate); gp7, gp8 (intermediate baseplate); gp9, gp10, gp11, gp12 (peripheral); gp48 and gp54 (proximal region of the tail tube).3 Publications
