Human Serum Cholinesterase, a Tetramer

Nature New Biology, 1972
AFTER electrophoresis of human serum in starch gel1, there are at least four bands of Cholinesterase activity. Most of the enzyme is concentrated in the band with least mobility (C4) while three faster moving bands (C1, C2, C3) are of lower molecular weight as shown by gel filtration2.

Multiple forms of serum cholinesterase

Archives of Biochemistry and Biophysics, 1968
Abstract Two additional molecular forms of serum cholinesterase have been demonstrated in one of two purified enzyme sources. The other preparation revealed five components and occasionally revealed the extra bands. All components were converted to one major form by concentration. All forms hydrolyzed four substrates by the zymogram technique.

Serum Cholinesterase Activity in Hyperlipidemia and the In Vitro Effect of Isoniazid on Serum Cholinesterase

Canadian Journal of Biochemistry, 1972
Increased serum Cholinesterase activity was observed in hyperlipidemic patients. When hyperlipidemia was induced in rabbits by injecting the lipopolysaccharide of Escherichia coli, a significant rise in serum low density lipoproteins and Cholinesterase activity occurred.In vitro experiments demonstrated that isoniazid produced proportionate decreases ...

Atypical Serum Cholinesterase in The Netherlands

Human Heredity, 1976
Pseudocholinesterase was examined in 322 samples from unrelated, healthy blood donors. In 14 cases heterozygosity was found, i.e. the frequency of the allele for atypical cholinesterase amounts to 0.022. A comparison is made with other European populations.

Serum cholinesterase in obsessive-compulsive disorder

Psychiatry Research, 1995
Levels of serum cholinesterase (PsChe) were measured in 32 drug-free patients with obsessive-compulsive disorder (OCD) and 32 sex- and age-matched healthy normal volunteers. No significant differences between OCD patients and normal subjects were found in PsChe levels.

Structure of human serum cholinesterase

BioEssays, 1988
AbstractHuman cholinesterase has recently been sequenced and cloned. It is a glycoprotein of 4 identical subunits, each subunit containing 9 carbohydrate chains and 3.5 disulfide bonds. Protein folding is likely to be very similar in human cholinesterase and Torpedo acetylcholinesterase.

Human Serum Cholinesterase as a Sialo‐Protein

Acta Physiologica Scandinavica, 1961
AbstractIncubation of human serum with sialidase (neuraminidase, receptor destroying enzyme) results in a marked decrease of the mobility of cholinesterase without affecting the enzymatic activity as indicated by the splitting of acetylcholine and butyrylcholine.

Human Serum Cholinesterase

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1970
Summary 1. Human serum cholinesterase (EC 3.1.1.8) was purified about 500 times from reconstituted outdated plasma by (NH4)2SO4 acid precipitation and chromatography on DEAE-cellulose. The yield was 45%. 2. The enzyme system showed seven major components on polyacrylamide gel electrophoresis, six of which survived the purification procedure ...
