Dopamine beta-hydroxylase was incubated with p-hydroxybenzyl cyanide, ascorbate, and O2 and the products of the hydroxylation reaction were monitored by high performance liquid chromatography. At early times, p-hydroxymandelonitrile was the sole product but this compound slowly decomposed to p-hydroxybenzaldehyde and

When 3,4-dihydroxybenzylcyanide (DBC) is oxidized by mushroom tyrosinase, the first visible product, identified as the corresponding quinomethane, exhibits an absorption maximum at 480 nm. Pulse-radiolysis experiments, in which the o-quinone is formed by disproportionation of semiquinone radicals generated by single-electron

Defined insertion mutations have been constructed in the Rhizobium (Sinorhizobium) meliloti phbC gene, which encodes poly-beta-hydroxybutyrate (PHB) synthase. The locus was isolated and subcloned from a genomic library of R. meliloti Rm1021 by complementation of phbC mutation of Alcaligenes eutrophus.

In the present study analytical and preparative supercritical fluid chromatography (SFC) were used for investigation of myrosinase catalysed degradation of 4-hydroxybenzylglucosinolate (sinalbin). Sinalbin occurs as a major glucosinolate in seeds of Sinapis alba L., in various mustards and other food

Dopamine beta-hydroxylase (EC 1.14.17.1) is inactivated by p-hydroxybenzylcyanide (PHBC) in a manner characteristic of a suicide substrate. The inactivation 1) is first order in inhibitor (Kd = 1.9 mM, k2 = 0.05 min-1, pH 5.0), 2) exhibits saturation kinetics, and
