Protein unfolding: mitochondria offer a helping hand
Nature Structural Biology
|December 3, 1999
Summary
Mitochondrial protein import needs proteins to be unfolded. Researchers mapped this unfolding pathway, revealing it differs from spontaneous unfolding, offering insights into protein translocation energetics.
Area of Science:
- Mitochondrial biology
- Protein biophysics
Background:
- Mitochondrial protein import is essential for cellular function.
- Proteins must be unfolded to cross the mitochondrial membrane.
Discussion:
- This study maps the unfolding pathway of a specific mitochondrial cargo protein.
- The mitochondrial-assisted unfolding pathway was compared to the spontaneous unfolding pathway.
Key Insights:
- The cargo protein's unfolding pathway in mitochondria deviates from its spontaneous pathway.
- This deviation provides critical data on the energetics of mitochondrial protein translocation.
Outlook:
- Further research can explore how other proteins navigate mitochondrial import.
- Understanding these pathways could inform therapeutic strategies for mitochondrial diseases.

Overview
03:00Molecular Chaperones and Protein Folding
The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.

01:19Translocation of Proteins into the Mitochondria
Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

01:12Porin Insertion in the Outer Mitochondrial Membrane
Porins are beta-barrel proteins translocated to the mitochondrial outer membrane through the TOM complex into the intermembrane space. Porin precursors bind TIM chaperones within the intermembrane space and are guided to the Sorting and Assembly Machinery complex or SAM complex on the outer mitochondrial membrane.
Three models describe the assembly of porins by the SAM complex and their insertion into the outer membrane. Model 1 suggests that porins are assembled outside the SAM channel as the...

01:25Protein Folding
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.
