WebFeb 23, 2016 · The mechanism of action of the manganese-dependent phosphotriesterase from Sphingobium sp. strain TCM1 that is capable of hydrolyzing organophosphate flame retardants was determined. Phosphotriesterase is a membrane-associated protein that is translated with a 29 amino acid-long target peptide (Tat motif), which is then cleaved from the mature protein after insertion in the plasma membrane. The protein is anchored to the inner membrane of the cell, facing the periplasm.
