The Escherichia coli, Bacillus stearothermophilus, and human manganese-containing superoxide dismutases (MnSODs) and the E. coli iron-containing superoxide dismutase (FeSOD) are extensively inactivated by treatment with phenylglyoxal, an arginine-spe

The Cu,Zn superoxide dismutases from bovine liver, yeast, Caulobacter crescentus, and Photobacter leiognathi were compared for their susceptibilities to inhibition by cyanide and to inactivation by hydrogen peroxide and phenylglyoxal. All of these en

Yeast Cu,Zn superoxide dismutase is inactivated by H 2 O 2 at alkaline pH, and complete inactivation correlates with the modification of 1.0 histidine per subunit. At elevated concentrations of H 2 O 2 , a saturation process is evident and is charact

4-Hydroxy-3,5-dinitroacetophenone anion inhibits erythrocyte anion transport with a K 50 of 220 μ m in 165 m m KCl, pH 7.3, at 0°C. Substitution of bromine atoms on the α-carbon greatly enhances the inhibitory potency of this class of compounds. T

We have studied the spectroscopic and anion-binding properties of bovine and yeast Cu,Zn superoxide dismutases which have been chemically modified at one arginine per subunit by phenylglyoxal. This modification is known to inactivate these proteins a

Phosphoglycerate mutase is inactivated by butanedione in borate buffer. Inactivation by 0.13 mM reagent correlates with the modification of one arginyl residue per subunit, and is prevented by either 2, 3-diphosphoglycerate or 3-phosphoglycerate. Wit

Yeast enolase is rapidly inactivated by butanedione in borate buffer, complete inactivation correlating with the modification of 1. 8 arginyl residues per subunit. Protection against inactivation is provided by either an equilibrium mixture of substr

β-Lactamase (EC 3.5.2.6: penicillin amido-β-lactam hydrolase) I from B. cereus 569 H is inactivated by treatment with phenylglyoxal. Inactivation depends on the pH and the presence of bicarbonate in a manner which suggests that it is due to the mod

We wish to report that tryptophan modified with dimethyl (2-hydroxy-5-nitrobenzyl)-sulfonium bromide is stable to conditions of acid hydrolysis with 3 N p-toluenesulfonic acid. This technique of hydrolysis can thus be applied to quantitatively determ
