Selection of MDM2-binding peptides in Escherichia coli using an engineered split intein and aminoglycoside phosphotransferase†
Abstract
A protein trans-splicing (PTS)-based method for screening the peptides capable of binding to a target protein was developed using an engineered split intein and an aminoglycoside phosphotransferase. Two peptides selected against MDM2 bind to MDM2 with high affinity and a peptide can induce apoptosis in SJSA-1 cells.
