Ribosomes: are ribonuceloprotein structures comprised of rrna and protein. they have catalytic activity because their rna component makes them a ribozyme. are made of a small and a large subunit. in prokaryotes, the whole ribosome is known as a 70s ribosome, composed of a 50s large subunit and a 30s small.
Rio2p may function as an atpase rather than a kinase and while its catalytic activity is not required for its association with pre-40s particles, it promotes rio2p dissociation . tsr1p release then occurs following 80s-like ribosome formation and requires the intervention of the adenylate kinase/atpase fap7p.
