Stimulation of mammalian adenylate cyclase activity with guanosine 5′-tetraphosphate and other guanine nucleotides

Biochimica et Biophysica Acta (BBA) - General Subjects, 1978
Guanosine 5'-tetraphosphate (GTP4) stimulated mammalian adenylate cyclase activity at concentrations down to 1 micronM. Greater stimulatory activity was apparent with lung than with heart, brain or liver from the rat. At a concentration of 0.1 mM, GTP4 stimulated lung adenylate cyclase activity from rat, guinea pig and mouse about four-fold.

Adenosine-5'-tetraphosphate and guanosine-5'-tetraphosphate: new substrates of the cytosolic exopolyphosphatase of the yeast Saccharomyces cerevisiae.

Biochemistry. Biokhimiia, 1998
A cytosolic preparation of Saccharomyces cerevisiae is capable of hydrolyzing adenosine-5'-tetraphosphate and guanosine-5'-tetraphosphate with activities which are 1.5-2 times greater than that with polyP15. The apparent K(m) values for hydrolysis of adenosine-5'-tetraphosphate and guanosine-5'-tetraphosphate are 100 and 80 microM, respectively.

Inhibition of mammalian soluble guanylate cyclase activity by adenosine 5'-tetraphosphate, guanosine 5'-tetraphosphate and other nucleotides.

Journal of cyclic nucleotide research, 1977
The effects of a variety of purine and pyrimidine nucleotides were tested for their capacity to inhibit mammalian soluble guanylate cyclase activity. Adenosine 5'-tetraphosphate (ATetP), ATP, ADP, AMP, guanosine 5'-tetraphosphate (GTetP) and GDP were found to inhibit soluble guanylate cyclase activity from rat lung and other mammalian tissues.
