Crystal structure of the C-terminal domain of the bacteriophage T4 gene product 10
|
OverviewOverview
The success of tailed bacteriophages to infect cells far exceeds that of, most other viruses on account of their specialized tail and associated, baseplate structures. The baseplate protein gene product (gp) 10 of, bacteriophage T4, whose structure was determined to 1.2 A resolution, was, fitted into the cryo-electron microscopy structures of the pre and, post-infection conformations of the virus. gp10 functions as a molecular, lever that rotates and extends the hinged short tail fibers to facilitate, cell attachment. The central folding motif of the gp10 trimer is similar, to that of the baseplate protein gp11 and to the receptor-binding domain, of the short tail fiber, gp12. The three proteins comprise the periphery, of the baseplate and interact with each other. The structural and, functional similarities of gp10, gp11, and gp12 and their sequential order, in the T4 genome suggest that they evolved separately, subsequent to gene, triplication from a common ancestor. Such events are usual in the, evolution of complex organelles from a common primordial molecule.
