Identification of a chaperonin-10 homologue in plant mitochondria
1Department of Plant Sciences, University of Oxford, UK.
Abstract:
Chaperonin-60 and chaperonin-10 form stable binary complexes in the presence of ATP. This phenomenon has been used as the basis for the identification of a chaperonin-10 homologue in potato (Solanum tuberosum L.) mitochondria. ATP-dependent binary complexes formed between chaperonin-60 and chaperonin-10 in potato mitochondrial extracts were isolated by affinity chromatography on a column of immobilised chaperonin-60 antibodies. Partial amino acid sequence analysis of the chaperonin-10 protein indicates that it is related in primary structure to rat mitochondrial chaperonin-10.

Translocation of Proteins into the Mitochondria
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,...

Protein Transport to the Outer Chloroplast Membrane
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.
