Isozymes of Phenylalanine Hydroxylase
Science, 1972Three isozymes of phenylalanine hydroxylase exist in adult rat liver. They are chromatographically unique. Partial characterization suggests that they are similar in chemical properties and differ only in charge. Estimation of the Stokes radii indicates that the isozymes have similar molecular weights of about 200,000. Two isozymes exist in human fetal

We determined concentrations of alpha and gamma-enolases in normal testis and in seminoma tissues by enzyme immunoassay. Concentrations of alpha-enolase were 4,170 +/- 2,040 ng/mg protein in normal testis (n = 8) and 8,140 +/- 4,480 ng/mg protein in seminoma (n = 8).

IT has previously been observed that crystalline salivary amylase gives two peaks in free electrophoresis1. The work recorded here shows that a sample of salivary amylase crystallized three times, which gave a single peak in the ultracentrifuge (Fig. 1), could be separated into four bands by disk electrophoresis on polyacrylamide gel2 (Fig. 2).

Isozyme Specificity to Temperature
Nature New Biology, 1972TEMPERATURE treatment of styles leads to self-compatibility in otherwise self-incompatible species of Oenothera2,3, Lilium4 and Trifolium5,6. I have studied the temperature treatment of esterase in styles of several species and hybrids of Lilium by using gel electrophoresis.

AMP deaminase (AMP aminohydrolase EC, 3.5.4.6) catalyzes deamination of AMP to form IMP and ammonia. Although the physiological role of this enzyme remains obscure, it may be important to stabilize the adenylate charge (1), in the conversion of adenine nucleotide to inosine or guanine nucleotide (2–5) and furthermore as a key enzyme in the purine ...

European Journal of Cancer (1965), 1966
Abstract There are two different types of aldolase in mammalian tissues, the main difference between these isozymes is the relative activity towards the second substrate of aldolase, fructose- 1 -phosphate (F- 1 -P). In normal liver the ratio of the activities towards fructose di-phosphate (F-d-P) and towards fructose- 1 -phosphate, is near 1 ...

Isozymes of Alcohol Dehydrogenases
1980Thirty amino acid substitutions are known in eight sets of isozymes or mutants of alcohol dehydrogenases. The replacements are at different positions in the subunits and affect many regions of the protein chains, which is consistent with the variability in properties of isozyme pairs.

Electrophoretic technique combined with enzyme-specific stains has provided the most precise way of estimating genetic variability in many plant taxa. Within the genus Lycopersicon this method has been successfully applied by Rick and his colleagues for measuring the extent of variation both in cultivated forms and wild species (Rick 1976a, 1983 ...
