Structure of mandelate racemase with bound intermediate analogues benzohydroxamate and cupferron. [PDF]
Biochemistry, 2012 Mandelate racemase (MR, EC 5.1.2.2) from Pseudomonas putida catalyzes the Mg(2+)-dependent interconversion of the enantiomers of mandelate, stabilizing the altered substrate in the transition state by 26 kcal/mol relative to the substrate in the ground state.

Flotation and adsorption studies of chalcopyrite with cupferron [PDF]
International Journal of Mineral Processing, 1982 Abstract Flotation tests were conducted in a Hallimond tube on chalcopyrite, with a collector system of cupferron and fuel oil. The reagent concentration, pH and conditioning time were studied as variables. The necessity of the fuel oil was verified by conducting experiments without it.

Iron Coordination Properties of Gramibactin as Model for the New Class of Diazeniumdiolate Based Siderophores. [PDF]
Chemistry, 2021 The sequestration properties of gramibactin as a prototype for the new class of diazeniumdiolate siderophores is presented and compared with siderophores derived from catecholates and hydroxamates. According to pFe and pL0.5 values, gramibactin is a considerably more potent sequestering agent than the known class of phytosiderophores and approximately ...
