Einsteinium 123-125 monoamine oxidase B Bos taurus 39-44 8003474-18 1994 The rate of MAO B reduction by meta-substituted benzylamine analogues is essentially independent of the nature of the substituent. benzylamine 48-59 monoamine oxidase B Bos taurus 12-17 8003474-20 1994 These data demonstrate the steric orientation of the substrate to be important in the rate of amine oxidation by MAO B and that ring meta substituents favor this orientation.
