The physiological alpha-oxoaldehyde methylglyoxal binds and modifies arginine, lysine, and cysteine residues in proteins. The kinetics and mechanism of these reactions were investigated with N alpha-acetylamino acids and bovine serum albumin at pH 7.4 and 37 degrees C. The reaction
Clavaminate synthase (CAS), a remarkable Fe(II)/2-oxoglutarate oxygenase, catalyzes three separate oxidative reactions in the biosynthesis of clavulanic acid, a clinically used inhibitor of serine beta-lactamases. The first CAS-catalyzed step (hydroxylation) is separated from the latter two (oxidative cyclization/desaturation) by the

The butter flavorant diacetyl (2,3-butanedione) is implicated in causing obliterative bronchiolitis in microwave popcorn plant workers. Because diacetyl modifies arginine residues, an immunological basis for its toxicity is under investigation. Reaction products of diacetyl with N-α-acetylarginine (AcArg) were determined as

A strain of streptomycete isolated from a soil sample was found to produce a novel amino acid metabolite. The compound was purified from the culture fluid by chromatography, using cation exchange resin, a synthetic adsorbent, and finally by preparative HPLC

The concentrations of guanidino compounds in blood are raised in uraemic patients and may have toxic effects. The concentrations of 13 guanidino compounds in serum were measured in 29 patients with chronic renal failure treated by chronic intermittent haemodialysis using
