Genetics of Leucine Aminopeptidase Isozymes in Maize.
a combination of starch gel electrophoresis and various enzyme staining BLhniques multiple molecular forms of enzymes have been demonstrated in a large variety of organisms. MARKERT and MBLLER (1959) introduced the concept of an isozyme, defined as one of the molecular forms of an enzyme. In maize some highly interesting results have been found concerning esterase (SCHWARTZ 1960a, 1962~1, b, 19...
متن کاملUmbelliferone in Needles of Picea abies *
Umbelliferone, Quantitative Estimation, Picea abies, Genetic Families A compound showing blue fluorescence under UV-light was isolated from spruce needles and identified as umbelliferone. Structure analysis was based on UV and mass spectroscopy as well as chromatographic comparison with authentic material. Quantitative evaluation by direct measure ment of the fluorescence of the umbelliferone ...
متن کاملDevelopment in Norway Spruce, Picea abies'
A pulse-treatment of embryos of Picea abies (L.) Karst with cytokinin efficiently and reproducibly induces the coordinate de novo formation of bud primordia from subepidermal cells. The cytokinin treatment also affects the germinative development of the embryo; chloroplast maturation is delayed, and cell elongation is completely suppressed. We have analyzed the protein patterns in developing sp...
متن کاملLeucine Aminopeptidase (Bovine Lens)
The stability to pH and denaturing agents of crystalline leutine aminopeptidase (bovine lens) (EC 3.4.1.1) is reported. The native enzyme exhibited a molecular weight of 327,000. In 7 M urea below pH 3 and in 23.7 M guanidinium chloride below pH 8.5, both leucine aminopeptidase and its reduced and carboxamidomethylated derivative exhibited a molecular weight on equilibrium centrifugation of 54,...
متن کاملLeucine Aminopeptidase (Bovine Lens)
Spark emission and atomic absorption spectroscopy of crystalline leucine aminopeptidase (bovine lens) (EC 3.4.1.1) shows the presence of 2 zinc atoms per subunit molecular weight of 54,000 (12 zinc atoms per oligomer of 320,000). Removal of zinc by dialysis yields a zinc-free product with no enzymatic activity which upon readdition of Zn2+, regains full activity with the concomitant binding of ...
