1 Cited Publications
Customer Review

Based on 1 publication(s) in Google Scholar

The GSTA1 protein catalyzes the attack of glutathione on various compounds, forming conjugates of PGA2 and PGJ2. It also converts AD into D4-androstene-3,17-dione, contributing to hormone biosynthesis. Additionally, it participates in the metabolism of oxidized linoleic acid through its peroxidase activity against 13-HPODE. GSTA1 Protein, Human (HEK293, His) is the recombinant human-derived GSTA1 protein, expressed by HEK293 , with C-6*His labeled tag.

Biological Activity

Description

The GSTA1 protein catalyzes the attack of glutathione on various compounds, forming conjugates of PGA2 and PGJ2. It also converts AD into D4-androstene-3,17-dione, contributing to hormone biosynthesis. Additionally, it participates in the metabolism of oxidized linoleic acid through its peroxidase activity against 13-HPODE. GSTA1 Protein, Human (HEK293, His) is the recombinant human-derived GSTA1 protein, expressed by HEK293 , with C-6*His labeled tag.

Background

The GSTA1 Protein serves as a glutathione S-transferase, catalyzing the nucleophilic attack of the sulfur atom of glutathione on the electrophilic groups of a broad spectrum of both exogenous and endogenous compounds (Probable). This enzymatic activity includes the formation of glutathione conjugates for prostaglandin A2 (PGA2) and prostaglandin J2 (PGJ2). Additionally, GSTA1 plays a role in hormone biosynthesis by catalyzing the isomerization of D5-androstene-3,17-dione (AD) into D4-androstene-3,17-dione. Notably, its glutathione-dependent peroxidase activity extends to the metabolism of oxidized linoleic acid, specifically targeting the fatty acid hydroperoxide (13S)-hydroperoxy-(9Z,11E)-octadecadienoate/13-HPODE. The diverse enzymatic functions of GSTA1 underscore its involvement in crucial cellular processes, from detoxification reactions to hormone biosynthesis and the metabolism of oxidized lipids.

Verified Bioactivity

Specific activity is 4206.22 pmoL/min/μg, and is defined as the amount of enzyme that conjugate 1 pmole of 1-chloro-2,4-dinitrobenzene (CDNB) with reduced glutathione per minute at pH 6.5 at 25°C.
