The basic properties of purified d-amino acid oxidase from the yeast Trigonopsis variabilis were investigated. The pH optimum of activity was between pH 8.5 and 9.0, and the native molecular masses of holo- and apo-enzyme were determined to be 170 kDa; higher aggregates corresponded to molecular masses of 320 and 570 kDa. The apparent V max and K m values for different substrates varied between 3.7 to 185 U/mg and 0.2 to 17.3 mM, respectively. The reaction of d-amino acid oxidase with sulfite… CONTINUE READING
