Protein
Translocase of chloroplast 34 homolog, chloroplastic
Organism
Chlamydomonas reinhardtii
Function
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 (By similarity). Functions as an essential component of the outer chloroplast membrane translocon (TOC) complex, which, in turn, catalyzes the import of nucleus-encoded precursor polypeptides from the cytoplasm to the chloroplast (PubMed:23167510).
Similarity
Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. AIG1/Toc34/Toc159-like paraseptin GTPase family. TOC34 subfamily.
