The reaction of a class I ribonucleotide reductase (RNR) begins when a cofactor in the β subunit oxidizes a cysteine residue ~35 Å away in the α subunit, generating a thiyl radical. In the class Ic enzyme from Chlamydia trachomatis (Ct), the cyste

Recent kinetic measurements of the oxidation of linoleic acid by soybean lipoxygenase show that the thermal rate constants, kH ) 280 ((12) s -1 and kD ) 5.0 ((0.1) s -1 , are weakly temperature dependent within the temperature interval 30-50 °C. The

Methyl-coenzyme M reductase (MCR) catalyzes the chemical step of methane formation by methanogenic organisms. The reaction involves the two-electron reduction of CH{sub 3}S-CoM by N-7-mercaptoheptanoylthreoinine phosphate (CoB-SH). The authors have e

Our search for new organic superconductors has led us to explore the suitability of large polyfluorinated anions, in analogy to these perfluorinated organometallic complex anions. In this paper, we report the discovery of superconductivity (diamagnet
