Inhibition of ribulose diphosphate carboxylase/oxygenase by xylitol 1,5-diphosphate

Biochemical and Biophysical Research Communications, 1975
Summary Xylitol 1,5-diphosphate is a potent inhibitor of RuDP carboxylase/oxygenase activity. At an enzyme concentration of 400 μg/ml (less than 1 μM), RuDP carboxylase is inhibited 50% by 2 μM xylitol 1,5-diphosphate. The molar ratio of effector to enzyme is 2 to 1. The inhibition with respect to RuDP is mixed uncompetitive and noncompetitive.

Inhibition of thiamin diphosphate dependent enzymes by 3-deazathiamin diphosphate

Organic & Biomolecular Chemistry, 2004
3-Deazathiamin diphosphate (deazaTPP) and a second thiamin diphosphate (TPP) analogue having a benzene ring in place of the thiazolium ring have been synthesised. These compounds are both extremely potent inhibitors of pyruvate decarboxylase from Zymomonas mobilis; binding is competitive with TPP and is essentially irreversible even though no covalent ...

Polyprenyl Diphosphate Synthases

1997
It is noteworthy that in spite of the similarity of the reactions catalyzed by these prenyltransferases, the modes of expression of catalytic function are surprisingly different, varying according to the chain length and stereochemistry of reaction products. These enzymes are summarized and classified into four groups, as shown in Figure 13.

[107] Isolation of uridine diphosphate glucose, uridine diphosphate acetylglucosamine, and guanosine diphosphate mannose

1963
Publisher Summary This chapter describes the isolation of uridine diphosphate glucose, uridine diphosphate acetylglucosamine, and guanosine diphosphate mannose. The basic principle is that alcoholic extract from toluene-autolyzed yeast is fractionated on anion-exchange columns.

Estimation of hexose diphosphate

Archives of Biochemistry and Biophysics, 1954
Abstract A new method based on the anthrone reaction is proposed for the quantitative determination of hexose diphosphate in order to eliminate the uncertain fructose equivalent. The method can he used for determination of hexose diphosphate of 5–400 μg. with an experimental error for a duplicate determination of 2.4%.

Measurements of uridine diphosphate glucose and uridine diphosphate galactose — an appraisal

European Journal of Pediatrics, 1995
The recent disproof of a major deficiency of uridine diphosphate galactose in galactosemia should not lead investigators to assume either that enzymatic methods are unreliable for uridine sugar assays or that a defect in galactosylation in galactosemia has been excluded.

Geranylgeranyl diphosphate synthase catalyzing the single condensation between isopentenyl diphosphate and farnesyl diphosphate.

Journal of biochemistry, 1993
Geranylgeranyl diphosphate synthase was purified 191-fold from bovine brain by Mono Q column chromatography followed by preparative isoelectric focusing electrophoresis and Superose 12 gel filtration. The synthase had a pI value at 6.0, and it was made free of farnesyl diphosphate synthase, the pI of which was 5.1.
