AmtB - Substrate specificity
SURFE2R N1 data and applications:
Purified AmtB from E.Coli was incorporated into liposomes and used on the SURFE2R N1. AmtB substrate specificity. (A) Transient current measured after a 100 mM substrate jump. Ammonium (red), methylammonium (black), potassium (green) or sodium (purple). Potassium and sodium do not act as substrates for AmtB and methylammonium translocates but at a much reduced rate compared with ammonium. Insert: Normalised current after a 100 mM substrate jump. Ammonium (red), methylammonium (black).
