SYNONYMS
Glutaredoxin-2, Grx2, grxB, b1064, JW1051.
INTRODUCTION
Glutaredoxin-2 (GrxB) is amember of the glutaredoxin family. Glutaredoxins are small redox enzymes of approximately 100 amino-acid residues which use glutathione as a cofactor. Glutaredoxins are oxidized by substrates, and reduced non-enzymatically by glutathione. GrxB is involved in reducing some disulfides in a coupled system with glutathione reductase. GrxB doesn’t act as hydrogen donor for ribonucleotide reductase.
DESCRIPTION
GRXB produced in E.Coli is a single, non-glycosylated polypeptide chain containing 235 amino acids (1-215 a.a.) and having a molecular mass of 26.5kDa.
GRXB is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
