D-glyceraldehyde 3-phosphate dehydrogenases of higher plants.
The d-glyceraldehyde 3-P dehydrogenases of spinach leaf, pea seed, and pea shoot were purified. The NADP and NAD-linked enzymes of either spinach leaves and pea shoots could not be separated. Changes in the ratio of NADP- to NAD-linked activity of the spinach leaf and pea shoot enzymes were observed during both purification and storage of crude extracts. The spinach leaf, pea shoot, and pea see...
متن کاملNonreversible d-Glyceraldehyde 3-Phosphate Dehydrogenase of Plant Tissues.
Preparations of TPN-linked nonreversible d-glyceraldehyde 3-phosphate dehydrogenase (EC 1.2.1.9), free of TPN-linked reversible d-glyceraldehyde 3-phosphate dehydrogenase, have been obtained from green shoots, etiolated shoots, and cotyledons of pea (Pisum sativum), cotyledons of peanut (Arachis hypogea), and leaves of maize (Zea mays). The properties of the enzyme were similar from each of the...
متن کاملGlyceraldehyde 3-Phosphate Dehydrogenases and Glyoxylate Reductase: II. Far Red Light-Dependent Development of Glyceraldehyde 3-Phosphate Dehydrogenase Isozyme Activities in Sinapis Alba Cotyledons.
Ammonium sulfate chromatography has been employed to separate glyceraldehyde 3-phosphate dehydrogenases (GPD) of Sinapis alba cotyledons of various developmental stages. Cotyledons of dark-grown seedlings possess one major NAD-specific enzyme designated NAD-GPD I. Irradiation with continuous far red light leads to a strong increase in NADP-GPD activity and to the formation of a second NAD activ...
متن کاملHigh-resolution structure of human D-glyceraldehyde-3-phosphate dehydrogenase.
GAPDH (D-glyceraldehyde-3-phosphate dehydrogenase) is a multifunctional protein that is a target for the design of antitrypanosomatid and anti-apoptosis drugs. Here, the first high-resolution (1.75 Angstroms) structure of a human GAPDH is reported. The structure shows that the intersubunit selectivity cleft that has been leveraged in the design of antitrypanosomatid compounds is closed in human...
متن کاملThe glyceraldehyde 3-phosphate dehydrogenases of liver and muscle. Cooperative interactions and conditions for functional reversibility.
A method is described for the isolation of glyceraldehyde 3.phosphate dehydrogenase from rabbit liver. The enzyme has been crystallized as the NAD complex and its chemical and physical properties have been compared with those of the muscle enzyme. The kinetics of the reversible reaction catalyzed by the dehydrogenases is sensitive to temperature and ionic strength and has been examined at 37, p...
