Comments [?]

case <OG:Organellar chromatophore>
Function Promotes protein synthesis. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes.
else
Function Promotes chloroplast protein synthesis. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes.
end case
Catalytic activity RHEA:19669: GTP + H2O = GDP + H(+) + phosphate
EC 3.6.5.n1
case <OG:Organellar chromatophore>
Subcellular location Plastid, organellar chromatophore.
else
Subcellular location Plastid, chloroplast.
end case
case not <OG:Organellar chromatophore> and not <AnyFeature:TransitC>
Miscellaneous This protein may be expected to contain an N-terminal transit peptide but none has been predicted.
end case
Similarity Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. LepA subfamily.
