Purification of S-methyl-L-methionine : homocysteine methyltransferase in Triticum aestivum (Gramineae)Bryan, James E. January 1976 (has links)
Two direct methyltransferase systems in winter wheat have been reported using partially purified enzyme extracts. In order to gain further understanding of these enzymes, such classical enzyme investigations as pH range and optimum pH, the calculation of average activation energies, and inhibition investigations need to be undertaken using more highly purified enzymes. The purpose of this investigation was to develop procedures for further purification of S-methyl-Lmethionine:homocysteine methyltransferase in order that future researchers might undertake such studies.

Initial characterization of a new histone and role of methionine in protamine biosynthesis in trout testisWigle, Donald Theodore January 1970 (has links)
Histones are the basic proteins complexed with DNA in the chromosomes of eukaryotic organisms. A previously undescribed histone (histone T.) was discovered in chromatin prepared from rainbow trout (Salmo gairdnerii) testes. Histone T was purified by selective extraction and ion-exchange chromatography on CM-cellulose. The homogeneity of this protein was examined by polyacrylamide disc gel electrophoresis, SDS disc gel electrophoresis, urea starch gel electrophoresis and gel filtration chromatography. Histone T was homogeneous as judged by the above different
criteria. The molecular weight was found to be 14,500 by the mobility of formylated or acetylated histone Ton SDS gel electrophoresis. The amino acid composition and the N-terminal amino acid were determined. Peptide maps of the tryptic peptides of histone T and the major histones indicated
that histone T is not a degradation product of the major histones.
Details of the mechanism of initiation of protein synthesis
in eukaryotes have only recently been discovered. Protamines are the small, highly basic proteins complexed with DNA in the mature sperm cells of most higher animals. The synthesis of protamine in trout testes was studied.
Cell suspensions prepared from trout testes at the protamine
stage of differentiation were incubated in vitro and were found to incorporate intact, isotopically labelled methionine into the N-terminal sequence, Met-Pro-Arg...,
methionine residue is removed from protamine after chain completion. Enzymatic activity capable of cleaving the dipeptide, Met-Pro, was found in testis cell fractions. The amino group of methionine incorporated into ribosome-bound nascent protamine was not blocked. Methionine incorporation
was extremely sensitive to inhibition by cyclo-heximide. The evidence obtained indicates a role for methionine
in the initiation of protamine biosynthesis in the trout, a eukaryote / Medicine, Faculty of / Medical Genetics, Department of / Graduate
