Wool Proteins

Starch-gel electrophoresis in 8M urea has been used to demonstrate the presence of many components in wool protein fractions extracted from reduced and alkylated wool. All preparations of low-sulphur wool proteins gave mUltiple bands on starch gel in 8M urea even though some of these had previously been fractionated to give a single peak using moving-boundary electrophoresis in the absence of 8M urea. The heterogeneity suggested by these results is in Rccord with that found by chromatography of the proteins on DEAE-cellulose in buffers containing 8M urea. With stepwise elution from DEAE-cellulose it is possible to obtain fractions responsible for various sections of the starch-gel electrophoretic pattern.

Sera from 354 Yorkshire and 97 Lacombe pigs on official Canadian Record of Performance test were analyzed by starch gel electrophoresis to determine their hemopexin, transferrin, prealbumin and albumin1 types. Estimates of the possible effects of different serum protein types on daily gain on test, age at slaughter adjusted to 70.37 kg carcass weight and seven other carcass characteristics were obtained by least squares methods. Significant associations were observed between each of the four serum protein loci and at least one of the nine productive traits in the Yorkshire breed. In the Lacombe breed only the prealbumin locus, which was associated with total backfat thickness, had any effect on any one of the nine productive traits. Since the results for the two breeds were not in agreement with each other and the magnitude of the difference between extremes was small, it was concluded that a correlated response in swine performance could not be expected from selection on the basis of serum protein polymorphism.

1. Ribosomal protein fractions from rabbit reticulocytes and rat liver were prepared by extracting ribosomes with 0.2n-hydrochloric acid or guanidinium chloride and subsequent dialysis. 2. Treatment for 2.5hr. or less with 0.2n-hydrochloric acid dissolved 46-54% of the proteins, which were richer in arginine and lysine and in N-terminal alanine groups and poorer in aspartic acid and glutamic acid and in N-terminal glycine groups than the acid-insoluble proteins. 3. Protein fractions prepared from the guanidinium chloride extract of ribosomes from rat liver were usually more basic than those from rabbit reticulocytes. 4. The ratios lysine: arginine of fractions in the guanidinium chloride extracts were appreciably higher for proteins from rabbit reticulocytes than from rat liver. 5. The concentration of urea and the pH of the gel affected the rate of migration and number of bands in starch-gel electrophoresis.

SummaryWhen urea or ε-amino caproic acid were used as solublizing agents for plasminogen in electrophoretic experiments, only one broad band of the proenzyme was obtained on acetate cellulose, in starch block, and in acrylamide gel. In starch gel electrophoresis, however, both forms of plasminogen – the native or euglobulin and Kline’s or Pseudoglobulin plasminogen – separated into six bands. These migrated toward the cathode at room temperature in borate or veronal buffer in the alkaline range and showed full activity in fibrinagar-streptokinase plates.

ABSTRACT The isozymic patterns of tyrosine aminotransferase, NADP malate dehydrogenase, NADP isocitrate dehydrogenase, and tetrazolium oxidase were examined by starch-gel electrophoresis in Tetrahymena pyriformis, syngen 1. The genetics of the alleles controlling these enzymes was studied through a breeding program. Each enzyme locus was shown to assort vegetatively, as do other loci in this organism. A detailed analysis of the assortment process for the tyrosine aminotransferase locus indicated that the rate of stabilization of heterozygotes into pure types was essentially identical to previously-reported rates for other loci.
