Protein

Translocase of chloroplast 33, chloroplastic

Gene
TOC33, PPI1, At1g02280, T7I23.11
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

GTPase involved in protein precursor import into chloroplasts. Seems to recognize chloroplast-destined precursor proteins and regulate their presentation to the translocation channel through GTP hydrolysis. Binds GTP, GDP, XTP, but not ATP. Probably specialized in the import of nuclear encoded photosynthetic preproteins from the cytoplasm to the chloroplast, especially during early development stages.10 Publications

Cofactori

Binds 1 magnesium ion by subunit.

Interactioni

Subunit structurei

Homodimer, heterodimer with TOC34 and TOC159, and monomer. The homodimerization and the dimerization with TOC159 require the binding of GTP on Arg-130, and a hypothetical coGAP factor. The dimeric form has a higher GTPase activity than the monomeric form. Part of the TOC core complex that includes 1 protein for the specific recognition of transit peptides surrounded by a ring composed of four proteins forming translocation channels, and four to five GTP-binding proteins providing energy. This core complex can interact with components of the TIC complex to form a larger import complex. Chloroplastic protein precursor such as prSS (precursor of the RuBisCO small subunit) interacts with these complexes. The TOC complex contains a specific subset of polar lipids such as digalactosyldiacylglyceride (DGDG), phosphatidylcholine (PC) and phosphatidylglycerol (PG). Interacts at least with TOC75-3. Forms large complexes including TOC33, pPORA and OEP161 during pPORA import into plastids at the plastid envelope membrane.9 Publications
