GP31 CO-CHAPERONIN FROM BACTERIOPHAGE T4
Overview
The Gp31 protein from bacteriophage T4 functionally substitutes for the, bacterial co-chaperonin GroES in assisted protein folding reactions both, in vitro and in vivo. But Gp31 is required for the folding and/or assembly, of the T4 major capsid protein Gp23, and this requirement cannot be, satisfied by GroES. The 2.3 A crystal structure of Gp31 shows that its, tertiary and quaternary structures are similar to those of GroES despite, the existence of only 14% sequence identity between the two proteins., However, Gp31 shows a series of structural adaptations which will increase, the size and the hydrophilicity of the "Anfinsen cage," the enclosed, cavity within the GroEL/GroES complex that is the location of the, chaperonin-assisted protein folding reaction.
