    Isocitric Lyase and Isocitric Dehydrogenase in Germinating Lettuce (1968)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 21 (1968), S. 0 
    Details
    ISSN: 1399-3054

    Topics: Biology
    Notes: A soluble isocitric lyase is shown to occur in lettuce seeds. Its activity increases during germination till 72 hours and then falls again. No particulate lyase could be detected. In addition both a soluble and a particulate isocitric dehydrogenase is present in the seeds. Both enzymes react with NAD as well as with NADP. The soluble enzyme drops sharply in activity during germination, while the particulate enzyme remains at a more or less constant level of activity. By gel electrophoresis the isocitric lyase and the isocitric dehydrogenase were shown to consist of what appear to be several isozymes. The interrelation between the enzymes and their relation to fat metabolism during germination is discussed. Evidence is brought for an enzymic reaction by which isocitric acid is converted to pyruvic acid. The nature of this reaction is not clear.

    Photosynthetic and Dark Fixation of 14CO2 in Detached Soybean Cotyledons (1967)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 20 (1967), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Detached soybean cotyledons fixed CO2 both in the light and dark. Carbon dioxide fixed by the light and dark reactions replaced only a small portion of CO2 lost by respiration up to the 10th day. In the dark most of the 14C label was found in the acidic fraction, while in the light 65 per cent of the activity was found in the neutral and basic fractions.

    Activation of Enzymes during Germination: Amylopectin-1,6-glucosidase in Peas (1968)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 21 (1968), S. 0 
    Details
    ISSN: 1399-3054

    Topics: Biology
    Notes: Development of amylopectin-1, 6-glucosidase (amylopectin 6- glucanohydrolase) activity in germinating peas occurs under conditions in which protein synthesis is inhibited and α- and β-amylase fail to increase in activity. An increase in activity of amylopectin 6-glucanohydrolase can be obtained in cell free homogenates of imbibed pea seeds under autolytic conditions. Activation is shown to occur in a particulate fraction and to be due to the action of a proteolytic enzyme in the homogcnates. A system could be constituted consisting of a particulate fraction and trypsin which lead to a rapid activation of the amylopectin 6-glucanohvdrolase. This is regarded as proof that enzymes in germinating seeds can be formed by liberation or activation of precursor forms. The implications of this are discussed.
