Guanosine-5?-triphosphate hydrolysis and tubulin polymerization
Molecular and Cellular Biochemistry, 1982GTP hydrolysis associated with polymerization is a distinctive feature of microtubule assembly. This reaction may be fundamentally linked to the dynamic properties of microtubules in vivo. Kinetic analysis of the connection between microtubule assembly and associated GTP hydrolysis indicates that these two events are kinetically uncoupled, GTP ...

Evidence for Guanosine Triphosphate—Binding Proteins in Trypanosoma cruzi
The American Journal of Tropical Medicine and Hygiene, 1994The transformation of the parasite Trypanosoma cruzi from the blood-borne trypomastigote to the intracellular amastigote constitutes a key clinical feature in the pathophysiology of Chagas' disease. That this transition occurs without change in the integrity of the plasma membrane of the parasite suggests the presence of biochemical structures, i.e ...

Structural and Functional Relationships of Guanosine Triphosphate Binding Proteins
1988Information available at present documents the existence of three well-defined classes of guanine nucleotide binding proteins functioning as signal transducers: Gs and Gi which stimulate and inhibit adenylate cyclase, respectively, and transducin which transmits and amplifies the signal from light-activated rhodopsin to cGMP-dependent phosphodiesterase

Light-induced phosphorylation of rod outer segments by guanosine triphosphate
Biochemical and Biophysical Research Communications, 1975Abstract Significant GTP-dependent protein kinase activity is present in isolated photoreceptors of the retina. No transfer of the γ- 32 P group from GTP-γ- 32 P to ATP was detected. Although no stimulation of GTP-kinase activity by cyclic GMP or cyclic AMP was observed, exposure of dark-adapted photoreceptors to light resulted in a 46-fold increase ...

Guanosine Triphosphate: 5-Hydroxylysine Phosphotransferase in Rat Kidney Cortex
Enzyme and Protein, 1977An enzyme which catalyzes the transfer of the 7-phosphate from GTP onto 5-hydroxylysine was partially purified from rat kidney cortex by means of acid precipitation and DEAE-Sephadex A-50 column chromatography. The enzyme activity was assayed by measuring the transfer of [32P] from γ-[32P]-GTP to materials not adsorbed by charcoal.
