[ | [https://www.uniprot.org/uniprot/TOC33_ARATH TOC33_ARATH] 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.<ref>PMID:11553737</ref> <ref>PMID:12741849</ref> <ref>PMID:12782294</ref> <ref>PMID:12869544</ref> <ref>PMID:12951325</ref> <ref>PMID:12897258</ref> <ref>PMID:15053763</ref> <ref>PMID:16412428</ref> <ref>PMID:16435266</ref> <ref>PMID:18054337</ref> | ||
