Why I Stamp:
Recombinant E. coli msrB Protein (DAG-P2942)
Like most bacteria, Escherichia coli expresses a single msrB (Methionine-R-sulfoxide reductase) that carries out the reduction of methionine-R-sulfoxide to methionine. The E. coli enzyme belongs to a group of MsrBs, that possess a metal binding site composed of two CXXC motifs. The bound metal (zinc or iron) may stabilize the conformation of the enzymes.
