Overview
Hsp60 is a mitochondrial chaperonin essential for protein folding within the mitochondrial matrix. It forms a double-ring barrel structure that provides an isolated environment for client protein folding, working in conjunction with Hsp10 as a co-chaperone.
Structure
Hsp60 forms a distinctive structure:
Heptameric rings: Two stacked rings of 7 subunits each
Barrel chamber: Central cavity for protein folding (~20 Å diameter)
ATP-binding domains: Each subunit contains ATPase activity
Co-chaperone binding: Hsp10 forms a lid for the chamber
The structure resembles a cylindrical chamber that encapsulates client proteins during folding.
Normal Function
Mitochondrial Protein Folding
Imports precursor proteins from cytosol
Folds proteins within protected chamber
Uses ATP hydrolysis for conformational changes
Releases correctly folded proteins
