| 英文摘要 | The oxidation processes of the radiation-generated, three-electron-bonded intermediates AcMet(2) [Sa ' S](+) and AcMet [Sa ' Br] were investigated by pulse radiolysis via their reactions with tryptophan (TrpH). These intermediates were derived from N-acetyl-methionine amide (N-AcMetNH(2)) and N-acetyl-methionine methyl ester (N-AcMetOMe). The bimolecular rate constant k of the reaction between each intermediate and l-tryptophan (TrpH) was measured. For N-AcMetNH(2), k for the reaction of AcMet(2) [Sa ' S](+) with TrpH were 3.4 x 10(8) and 2.2 x 10(8) dm(3) mol(-1) s(-1) at pH = 1 and 4.5, respectively. For N-AcMetOMe, k for the reaction of AcMet(2) [Sa ' S](+) with TrpH were 4.0 x 10(8) and 2.8 x 10(8) dm(3) mol(-1) s(-1) at pH 1 and 4.5, respectively. The rate constants for the intermolecular transformation of Met [Sa ' Br] into TrpH(+) or Trp were also estimated. For N-AcMetNH(2), k for the reaction of AcMet(2) [Sa ' Br] with TrpH were 2.6 x 10(8) and 3.3 x 10(8) dm(3) mol(-1) s(-1) at pH 1 and 4.5, respectively. Related mechanisms were discussed. |
