Descrição geral

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

Aplicação

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.
Agente caotrópico potente, útil para desnaturação e subsequente reenovelamento de proteínas. Este agente desnaturante potente é capaz de solubilizar proteínas insolúveis ou desnaturadas, como corpos de inclusão. Isso pode servir como a primeira etapa no reenovelamento de proteínas ou enzimas em suas formas ativas. Pode ser necessário também o uso de ureia e ditiotreitol (DTT).

Ações bioquímicas/fisiológicas

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
