Crystallization of a stringent response factor from Aquifex aeolicus [PDF]
, 2002 The crystallization of a key enzyme from Aquifex aeolicus with suggested bifunctional activity, acting as an exopolyphosphatase and a guanosine pentaphosphate phosphohydrolase, is reported.

Synthesis of Guanosine Tetra- and Pentaphosphate Requires the Presence of a Codon-Specific, Uncharged Transfer Ribonucleic Acid in the Acceptor Site of Ribosomes [PDF]
Proceedings of the National Academy of Sciences, 1973 The nucleotides ppGpp and pppGpp accumulate when wild-type, but not rel - , strains of Escherichia coli are starved for required amino acids. These compounds are synthesized on ribosomes, in the presence of the product of the rel gene, from GDP and GTP; ATP

Inositol hexaphosphate guanosine diphosphate phosphotransferase from Phaseolus aureus
, 1975 Inositol hexaphosphate guanosine diphosphate phosphotransferase which transfers phosphate from inositol hexaphosphate to guanosine diphosphate, synthesizing guanosine triphosphate, has been isolated from germinating mung bean.

A New Transfer RNA Fragment Reaction: TpΨpCpGp Bound to a Ribosome-Messenger RNA Complex Induces the Synthesis of Guanosine Tetra- and Pentaphosphates [PDF]
Proceedings of the National Academy of Sciences, 1974 The tetranucleotide TpΨpCpGp, when bound to Escherichia coli 50S ribosomal subunits, can replace intact tRNA in the stringent factor-directed synthesis of guanosine tetra- and pentaphosphates. The TpΨpCpGp-dependent fragment reaction has a strict requirement for the 50S and 30S ribosomal subunits and synthetic or ...
