General description

Guanidine hydrochloride (GdnHCl) is a well-known protein and enzyme denaturant. It is a small molecule and hydroscopic in nature.

Application

Agente caotrópico fuerte, útil para la desnaturalización y posterior replegamiento de las proteínas. Este fuerte desnaturalizante puede solubilizar las proteínas insolubles o desnaturalizadas como los cuerpos de inclusión. Esto puede utilizarse como el primer paso en el replegamiento de las proteínas o las enzimas a su forma activa. La urea y el ditiotreitol (DTT) también pueden ser necesarios.
Guanidine hydrochloride (GdnHCl) has been used as a component of the phosphate buffer saline (PBS) for the incubation of Schlemm′s canal (SC) cells. It has also been used as a component of the digestion buffer for the gelation and expansion of human HeLa229 cells. GdnHCl is also used to isolate RNA.

Biochem/physiol Actions

Guanidine hydrochloride (GdnHCl) is involved in conformational changes and loss of enzyme activity due to inactivation of the enzyme. It is involved in the loss of activity of alkaline phosphatase (ALPase) enzyme in Haliotis diversicolor. GdnHCl functions by hampering the activity of heat shock protein 104 (Hsp104) adenosine triphosphatase (ATPase) in vivo. It can also inactivate enzymes like papain and aminocyclase. Higher concentrations of GdnHCl leads to viral inactivation of herpes simplex virus 1 (HSV-1).

Septin proteins evolved from ancestral GTPases and co-assemble into hetero-oligomers and cytoskeletal filaments. In Saccharomyces cerevisiae, five septins comprise two species of hetero-octamers, Cdc11/Shs1-Cdc12-Cdc3-Cdc10-Cdc10-Cdc3-Cdc12-Cdc11/Shs1. Slow GTPase activity by Cdc12 directs the choice of incorporation of Cdc11 vs Shs1, but many
