S. enterica RidA and Rid2, but not Rid7, accelerate hydrolysis of imine products of L-amino acid oxidase. (A) Semicarbazone formation in assays containing leucine with or without 10 μM Rid protein. (B) Semicarbazone formation in assays containing leucine and various amounts of Rid protein. (C) Semicarbazone formation in assays containing various amino acid substrates and 10 μM Rid protein. Error bars indicate SE from at least three replicate assays. Data in B and C represent the amount of semicarbazone formation as a percent of control assays containing no Rid protein.
