Biological Reviews, 1972
Summary1. In this review, representative data on the nature of enzyme multiplicity and the developmental progressions of multiple enzyme forms have been collected, and the significance of this material has been discussed in relation to gene involvement during tissue differentiation.2.

Lung Phosphodiesterase Isoenzymes
1993The distinct phosphodiesterase isoenzyme activities in guinea-pig lung were identified and characterised. We demonstrate that protein kinase A catalyses the activation of lung Type V cyclic GMP phosphodiesterase. This occurs via a marked change in the Vmax for cyclic GMP hydrolysis.

Peroxidase isoenzymes in Linum
Theoretical and Applied Genetics, 1971Isoenzymes of peroxidase were separated on acrylamide gels in 2 genotypes of Linum usitatissimum L. and their F 1, F 2 and first backcross progeny. Active extracts were obtained from homogenates of main stem tissue; activity was measured both before and after electrophoretic separation.

Creatine kinase (CK), a widely distributed enzyme in the body, has its highest activities in skeletal muscle and myocardium; when serum CK activities are abnormally increased, injury to these organs must be part of the differential diagnosis. The isoenzyme CK-MB is the most important biochemical test in the diagnosis of acute myocardial infarction.

Isoenzymes of elapid acetylcholinesterases
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1977Abstract 1. Acetylcholinesterase activity of Naja naja naja, Naja melanoleuca and Bungarus fasciatus venoms is due to mixtures of isoenzymes. 2. Naja melanoleuca venom has two acetylcholinesterase isozymes and both Naja naja naja and Bungarus fasciatus venoms have four acetylcholinesterase isozymes that are resolved by disc gel ...

European Journal of Pediatrics, 1979
The amylase isoenzymes activities in serum and urine from 75 children treated for complications of mumps were evaluated. The clinical observations, especially in cases with suspected pancreatitis, were compared with the P- and S-type amylase activities.

Carcinoplacental isoenzyme antigens
Advances in Enzyme Regulation, 1973Abstract A carcinoplacental isoenzyme antigen is defined as a catalytically active protein present in a tumor, whose antigenic sites are identical to that of a protein present in the placenta but not in any fetal tissue. A family of placental isoenzymes of alkaline phosphatase (the Regan isoenzyme, the Nagao isoenzyme and Regan variant isoenzyme) is ...

DIAGNOSTIC DISSECTION BY ISOENZYMES
Pure and Applied Chemistry, 1961Alterations to plasma and serum enzymes represent subtle protein modifications associated with disease states. It appears that these enzyme activities are associated with two or more closely-related multimolecular forms which are, nevertheless, chemically, physically and immunologically distinctv-", These components, isoenzymes, can be measured ...
