Characteristics and behaviour of arylesterase in human serum and liver
European Journal of Clinical Investigation, 1977Abstract. Human arylesterase is localized in liver microsomes where the presence of different electrophoretic bands corresponding to the serum bands can be recognized.Serum arylesterase is mainly a result of liver activity and its high level might be explained by a low rate of elimination in urine.

Paraoxonase and arylesterase activities in coronary artery disease
European Journal of Clinical Investigation, 2006AbstractBackground Paraoxonase‐1 is an enzyme with three activities which are inversely related to cardiovascular diseases. Accordingly, the aim of the study was to investigate the paraoxonase, arylesterase activities and oxidative/anti‐oxidative status in coronary artery disease (CAD) and their correlation with the extent of CAD.Materials and methods

Cholinesterase, Arylesterase, and Lipoprotein Parameters in Twins
Acta geneticae medicae et gemellologiae: twin research, 1980A high heritability estimate was obtained for serum arylesterase activity level in a series of 40 male twin pairs (23 MZ, 17 DZ) aged 33–39 years. The heritability estimated for Cholinesterase activity was strikingly lower. In unrelated individuals a positive correlation between arylesterase, Cholinesterase, and various lipoprotein parameters appeared ...

Characterization of an arylesterase from Lactobacillus helveticus CNRZ32
Journal of Applied Microbiology, 2000An esterase gene (estA) was isolated from a previously constructed genomic library of Lactobacillus helveticus CNRZ32. The estA gene consisted of a 558 bp open reading frame encoding a putative peptide of 21.3 kDa. Protein sequence homology searches using BLAST revealed that EstA had low amino acid sequence identity with the serine-dependent ...

Inhibition of human serum arylesterase by metal chlorides
Journal of Inorganic Biochemistry, 2003The inhibition of arylesterase (paraoxonase, EC 3.1.8.1) by metal chlorides was studied with both pooled human serum (A phenotype) and purified enzyme, using phenyl acetate as substrate. Inhibition data were analysed with the Hill equation. Results obtained with whole serum and purified enzyme were very similar.

The Relationship between Arylesterase Activity and Growth in Rats
Acta Physiologica Scandinavica, 1970AbstractThere was a highly significant negative correlation between blood plasma arylesterase activity and growth rate in male rats when the enzyme activity was determined at younger ages (11–32 days). In females the correlation was only vaguely indicated. A direct or indirect causal relationship between the two parameters is discussed.

Plasma arylesterase activity in adults and newborn infants
Clinica Chimica Acta, 1962Abstract The arylesterase activity of human blood plasma was determined in samples from 64 normal adults, 45 pregnant women at parturition and 51 newborn infants. There was a considerable inter-individual variation in this activity in normal adults. No sex differences, no age variation and no differences between non-pregnant and pregnant individuals ...

Arylesterase and acetylcholinesterase in the erythrocytes of man, cow and pig
Biochimica et Biophysica Acta (BBA) - Enzymology, 1973Abstract 1. 1. The esterase activities of human, bovine and porcine erythrocytes have been determined gasometrically with phenyl acetate and acetylcholine iodide as substrates. The activity of human erythrocytes is twice that of bovine and porcine cells. Intact cells and hemolysates have about the same activity. The three species differ in regard

Age variation in plasma arylesterase activity in children
Clinica Chimica Acta, 1963Abstract The plasma arylesterase activity was determined in samples from 90 children of various ages (0 – 20 years). Children, two years or more of age, have the same arylesterase activity as normal adults. There is a steady increase in this activity during the first six months after birth, when the activity is significantly lower than in two-year ...

Stress-induced alterations in arylesterase activity in the rat
Biochemical Pharmacology, 1969Abstract Exposure of intact rats to emotional stress resulted in an increase of plasma arylesterase activity, more profound in males than in females. The intra class correlation of this effect between full-sibs suggests considerable maternal influence and/or additive genetic effects and dominance deviation, the additive part being minimal in females.
