Immobilisation of hydroxynitrile lyases
Hydroxynitrile lyases are a versatile group of enzymes that are applied both in the laboratory and on an industrial scale. What makes them particularly interesting is that to date five structurally unrelated categories of hydroxynitrile lyases have been ...

Pork liver has been shown to contain a soluble enzyme, L-fuconate hydro-lyase (L-fuconate dehydratase), capable of dehydrating L-fuconate to 2-keto-3-deoxy-L-fuconate. The enzyme has been partially purified. The Km for L-fuconate is 1.0 mM; D-arabonate is also an excellent substrate (Km 1.3 mM) but the enzyme is inactive with D-fuconate, L-arabonate ...

d‐Altronate hydratase and d‐mannonate hydratase belong to a class of Fe2+‐requiring enzymes, but the function of iron in these enzymes is largely unknown. Methods are described for the convenient preparation of both these hydratases from Escherichia coli and studies related to metal activation are presented.

[Individuality of mannonate and altronate hydro-lyases in Escherichia coli K 12].
Biochimie, 1975In Escherichia coli, mannonic and altronic hydrolyases act, respectively, on mannonate, the intermediate aldonate of the glucuronate branch, and on altronate the intermediate aldonate of the galacturonate branch of the hexuronate pathway, yielding 2-keto-3-deoxy-gluconate.

Abstract An experimental statistical design was used to determine cyanide concentration and time optima for the induction of formamide hydrolyase enzyme in a strain of Fusarium oxysporum isolated from a cyanide-containing industrial effluent. Fourteen experiments (including replicates) were carried out within an experimental domain with a cyanide ...

Summary 1. The activity of 5-aminolevulinate hydro-lyase (δ-aminolevulinate dehydratase) has been determined in lysates of human erythrocytes through the rate of formation of porphobilinogen. The precision of the method was ±2 percent. 2. Dithiothreitol at 3 mmol/liter was an effective activator of the enzyme. 3.

The properties of two enzymes involved in the shikimic acid pathway, dehydroquinate hydro-lyase and shikimate: NADP(+) oxidoreductase were studied in different species of higher plants (pteridophytes, gymnosperms, angiosperms) using chromatography on Sephadex G 100, DEAE cellulose, hydroxylapatite and isoelectric focusing.The two enzymes were not ...
