磷酰化甲硫氨酸与色氨酸之间电子转移的脉冲辐解研究

INTERMOLECULAR ELECTRON TRANSFER INVOLVING N PHOSPHORYL METHIONINE AND TRYPTOPHAN IN AQUEOUS SOLUTION: A PULSE RADIOLYSIS STUDY

用脉冲辐解动态吸收光谱法研究了Ｂｒ２·－、Ｃｌ２·－自由基引发Ｎ－二异丙基磷酰化甲硫氨酸（ＮＤＭ）与色氨酸（ＴｒｐＨ）的分子间电子转移机理，测定电子转移反应的速率常数，从分子结构观点解释了磷酰基对电子转移机理的影响。

In this paper, the intermolecular electrontransfer(ET) involving N phosphoryl methione(NDM) and tryptophan(TrpH) initiated by Br ·- 2 and Cl ·- 2 anion radicals in aqueous solutions have been studied using pulse radiolysis and kinetic spectrophotometric monitoring techniques, a series of rate constants of ET have been determined and the influence of N phosphoryl group on the mechanism of ET has been explained structurally
