  • Kinetics and Mechanism of Alkaline Hydrolysis of Y-Substituted Phenyl Phenyl Carbonates
    作者:Song-I Kim、So-Jeong Hwang、Eun-Mi Jung、Ik-Hwan Um

    Summary of second-order rate constants for reactions of Y-substituted phenyl benzoates ( 1a-j ) and Y-substituted phenyl phe-nyl carbonates ( 2a-j ) with OH – in 80 mol % H 2 O/20 mol % DMSO at 25.0 ± 0.1 o C a entry Y p K aY‐PhOH k OH‒ /M ‒1 s ‒1 12a 3,4-(NO 2 ) 2 5.42 98.9 794 b 4-NO 2 7.14 13.4 140 c 4-CHO 7.66 4.72 50.8 d 4-COMe 8.05 3.27 34.7 e 3-NO 2 8.35 5.97 - f 4-COOEt 8.503.1135.1 g 3-CHO
    已通过光谱法测量了Y取代的苯甲酸(2a-j)碱性解的二级速率常数< T പി >$(k_OH^-})$,并与先前报告的Y取代的苯甲酸(1a-j)相应反应的< T പി >$k_OH^-}$数值进行了比较。碳酸2a-j的反应性比1a-j高出8~16倍。Hammett图与< T Π >$\sigma^-$和< T Π >$\sigma^o$常数相关,但显示出许多散点,而Yukawa-Tsuno图则表现出良好的线性相关性,< T Π >$\rho$ = 1.21,< T Π >$\gamma$ = 0.33。因此,可以得出结论,该反应是通过一个协同机制进行的,其中离基团的排除仅稍微提前。然而,不能排除当前反应通过一个强迫协同机制及一个高度不稳定的中间体进行的可能性。

  • Do Electrostatic Interactions with Positively Charged Active Site Groups Tighten the Transition State for Enzymatic Phosphoryl Transfer?
    作者:Ivana Nikolic-Hughes、Douglas C. Rees、Daniel Herschlag
    DOI:10.1021/ja0480421
    日期:2004.9.1
    The effect of electrostatic interactions on the transition-state character for enzymatic phosphoryl transfer has been a subject of much debate. In this work, we investigate the transition state for alkaline phosphatase (AP) using linear free-energy relationships (LIFERs). We determined k(cat)/K-M for a series of aryl sulfate ester monoanions to obtain the Bronsted coefficient, beta(lg)., and compared the value to that obtained previously for a series of aryl phosphorothioate ester dianion substrates. Despite the difference in substrate charge, the observed Bronsted coefficients for AP-catalyzed aryl sulfate and aryl phosphorothioate hydrolysis (-0.76 +/- 0.14 and -0.77 +/- 0.10, respectively) are strikingly similar, with steric effects being responsible for the uncertainties in these values. Aryl sulfates and aryl phosphates react via similar loose transition states in solution. These observations suggest an apparent equivalency of the transition states for phosphorothioate and sulfate hydrolysis reactions at the AP active site and, thus, negligible effects of active site electrostatic interactions on charge distribution in the transition state.
