Sulphotransferases and phosphotransferases in insects
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1973Abstract 1. 1. High-speed supernatant fractions from tissue homogenates of eight species of insects representing four major orders were tested for sulphotransferase and phosphotransferase activities. 2. 2. A sulphotransferase system was present in all the species tested and required ATP, Mg 2+ and inorganic sulphate for the sulphation of p -

Biochimica et Biophysica Acta, 1960
Abstract The partial purification of the nucleoside phosphotransferase of carrot is described. The procedures, which entailed precipitation with acetone, fractionation with ammonium sulfate, and treatment with zinc ions in the presence of ethanol and with calcium phosphate gel, afforded preparations whose specific transferase activity was 40 to 100 ...

Assay of aminoglycoside phosphotransferase in situ
Analytical Biochemistry, 1985A method for the evaluation of the aminoglycoside phosphotransferase activity in bacterial colonies directly is described. The method is based on the ability of the enzyme to modify the substrate immobilized on carboxymethylcellulose paper. The sensitivity and accuracy of the method were tested by comparing the results of the present assay to those ...

Glucose phosphotransferase and intracelular trafficking
Molecular and Cellular Biochemistry, 1986Glycoproteins containing phosphodiester-linked glucose residues have recently been described. The synthesis of this structure occurs due to the intact transfer of alpha glucose-1-phosphate from UDP-glucose and is catalyzed by the enzyme glucose phosphotransferase (GlcPTase).

Nucleoside phosphotransferase of chick embryo
Molecular and Cellular Biochemistry, 1979This paper describes a purification procedure and some properties of a nonspecific nucleoside phosphotransferase of chick embryo, an activity which catalyzes the transfer of chick embryo, an activity which catalyzes the transfer of the phosphate ester from a deoxyribonucleotide or a pyrimidine ribonucleotide to a deoxyribonucleoside acceptor.

On the synthesis of nucleotides by nucleoside phosphotransferases
Biochimica et Biophysica Acta, 1954Abstract Various tissues contain enzymes catalyzing the transfer of phosphoric acid from low-energy organic phosphates to nucleosides, thereby effecting the synthesis of nucleotides. The behavior of the enzyme present in malt is studied with respect to pH, acceptor and donor concentrations, and inorganic phosphate effects.

The reaction of phosphages with ATP: Creatine phosphotransferase
Biochimica et Biophysica Acta (BBA) - Enzymology and Biological Oxidation, 1966Abstract 1. 1. A kinetic investigation has been made of the effect of various phosphagens on the reverse reaction catalysed by creatine kinase (ATP: creatine phosphotransferase, EC 2.7.3.2.). 2. 2. The results indicate that phosphoglycocyamine functions as a substrate of the enzyme with a maximum velocity only 0.18% of that obtained with ...

[71] Acyl phosphate: Hexose phosphotransferase (hexose phosphate: Hexose phosphotransferase)
1966Publisher Summary This chapter reveals that the acyl phosphate: hexose phosphotransferase is a constitutive enzyme in Aerobacter aerogenes PRL-R3 and is present in cells grown under a variety of conditions. The assay of choice involves the measurement of D-glucose 6-phosphate formed from D-glucose plus acetyl phosphate by coupling the reaction to ...

Transposable Neomycin Phosphotransferases
1977Transposable genetic elements are discrete DNA segments with the capacity to move between independent DNA replicons within the cell. The recent discoveries that certain plasmid-borne genes, which confer resistance to antibiotics and to heavy metals, are components of transposable elements has improved our understanding of how plasmids might pick up ...
