Biochem/physiol Actions

Guanosine 5′-tetraphosphate (G-tetra-P) may be used as a substrate to study the specificity and kinetics of polyphosphatases (triphosphate tunnel metalloenzymes (TTMs)) and exopolyphosphatases. Also used as an inhibitor to study the kinetics and mechanism of various guanylate cyclases. Guanosine 5′-tetraphosphate may be used in various studies with adenosine-5′-tetraphosphate.

We report the cloning, expression, purification, and characterization of the Trypanosoma cruzi exopolyphosphatase (TcPPX). The product of this gene (TcPPX), has 383 amino acids and a molecular mass of 43.1 kDa. TcPPX differs from most exopolyphosphatases in its preference for

Triphosphate tunnel metalloenzymes (TTMs) are a superfamily of phosphotransferases with a distinctive active site located within an eight-stranded beta barrel. The best understood family members are the eukaryal RNA triphosphatases, which catalyze the initial step in mRNA capping. The RNA

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.

Cytidine 5'-triphosphate synthase catalyzes the ATP-dependent formation of CTP from UTP using either NH(3) or l-glutamine (Gln) as the source of nitrogen. GTP acts as an allosteric effector promoting Gln hydrolysis but inhibiting Gln-dependent CTP formation at concentrations of >0.15

The second messenger systems involved in the final stages of the phototransduction cascade in Limulus photoreceptors remain unclear. Excised patches of transducing membrane contain cGMP-gated channels, suggesting the involvement of cGMP in the excitation process. To further explore this possibility
