Comments [?]

FUNCTIONIF-3 binds to the 30S ribosomal subunit and shifts the equilibrium between 70S ribosomes and their 50S and 30S subunits in favor of the free subunits, thus enhancing the availability of 30S subunits on which protein synthesis initiation begins.
case not <OG:Chloroplast>
end case
case <OG:Chloroplast>
SUBCELLULAR LOCATIONPlastid, chloroplast.
end case
SIMILARITYBelongs to the IF-3 family.
