title: ATPase and GTPase activities associated with the 5-S RNA-protein complex of Escherichia coli ribosomes.
abstract: Specific 5-S RNA-protein complexes were reconstituted from Escherichia coli 5-S RNA and 50-S ribosomal proteins. These complexes consist of 5-S RNA and two major proteins, namely E-L18 and E-L25. Analysis for enzymatic activities shows that ATP and GTP are hydrolyzed and that this hydrolysis is independent of elongation factors.
