GTP denotes guanosine triphosphate. Despite such promise, the potential therapeutic role of inhaled nitric oxide in adults remains uncertain; licensed indications are restricted to pediatric practice.

According to this model, mutant KRAS is able to hydrolyze guanosine triphosphate (GTP) and cycle between its active (GTP-bound) and inactive (guanosine diphosphate [GDP]–bound) states ...

Guanine is also a component of important biomolecules such as GTP (guanosine triphosphate), which is involved in cellular signaling and protein synthesis. In addition to their role in nucleic acids, ...
