Protein
Ribosome-binding factor PSRP1, chloroplastic
Organism
Spinacia oleracea
Function
Ribosome-binding factor involved in light- and temperature-dependent control of protein synthesis. Interacts with 16S sRNA nucleotides at the A-site and P-site, where it protects the decoding center and inhibits translation by preventing tRNA binding. Stabilizes 70S ribosomes against dissociation. May be recycled by the combined action of ribosome-recycling factor (RRF) and EF-G.
Similarity
Belongs to the HPF/YfiA ribosome-associated protein family. Long plastid HPF subfamily.
