Chapter 23, Problem 87P

Interpretation Introduction

Interpretation:

Give the structural formula for the reaction:

$\text{GTP}+{\text{H}}_{\text{2}}\text{O}\rightleftharpoons \text{GDP}+\text{Pi}$

Concept Introduction:

The G proteins are the receptor proteins and bind to the GTP, the binding of the GTP turns on the G protein and the hydrolysis of the GTP to GDP takes place. The GTP in presence of water is broken into GDP and phosphate ion, and give energy.
