Antioxidant protein GPX7

What is it?

Glutathione peroxidase7 (GPX 7) is an antioxidant enzyme in mammals in response to oxidative stress [1]. Oxidative stress essentially causes the aging of the skin and is typically caused by reactive oxygen species [2]. One of the reactive oxygen species that appear commonly on the human face is hydrogen peroxide. However, GPX7 can catalyze the reaction to reduce hydrogen peroxide to water and prevent the oxidation and aging of the skin [2],[3]. This is a way to nourish the skin in addition to the prevention of acne.

Usage and Biology

GPX7 is used for the nourishment of the skin, as it eliminates the presence of reacting oxygen species and hydrogen peroxide on the skin.

Characterization

Fig. 1. Characterization of GPx7 using Western Blotting
Lane M is the marker, and Lane 1 is the purified GPX7 from E .coli BL21. The weight of GPX7 is around 21 kDa [4], and the graph shows that the purified His-GPX7 indeed has a weight of around 21 kDa.
