Summary Introduction

To review:

Thefunction that guanine nucleotide exchange factors serves.

Introduction:

Guanine nucleotide exchange factors (GEFs) are proteins that activate monomeric GTPases via stimulating the release of guanosine diphosphate (GDP) to allow the binding of guanosine triphosphate (GTP). It plays an important role in the elongation phase of prokaryotic protein synthesis.
