Glutamate dehydrogenase (L-glutamate: NAD+ oxidoreductase (deaminating) EC 1.4.1.2) has been purified to homogeneity from Lemna minor and seeds of Pisum sativum. As established by polyacrylamide gel electrophoresis the Pisum-enzyme constitutes a multiple pattern of seven charge isoenzymes whereas the Lemna enzyme shows one single protein band. Molecular weights of 230 000 were calculated for bo...
The effect of methanolic extract of cashewnut (Anacardium occidentale) shell extract was seen on conidial germination of Erysiphe pisi and powdery mildew development in pea (Pisum sativum). Maximum conidial germination inhibition of E. pisi on glass slides was observed at 300 ppm. Similar effect on floated pea leaves was observed after 48 h at the same concentration. Conidial germination on int...
In root nodules of pea (Pisum sativum), endosymbiotic Rhizobium bacteroids are individually enclosed by a plant-derived membrane, the peribacteroid membrane, creating an organelle-like structure termed the symbiosome. In order to investigate the structure and function of the peribacteroid membrane in plant-microbe surface interactions, monoclonal antibodies were used to identify the major antig...
The repeated exposure of Pisum (pea) plants to red light brings into operation an apparent synthesis of phytochrome which is not observed in material kept in the dark. This process shows some temperature compensation but has an optimum at 26 degrees ; it is irreversibly inhibited by 10(-4)m cycloheximide and 10 mug/ml actinomycin D. It is also inhibited by the auxins indoleacetic acid, naphthal...
The effect of 96 h cold acclimation of pea (Pisum sativum L., cv. Ran 1) plants on their photosynthetic capacity was investigated. It was found that pea plants were able to modulate their photosynthetic rate during growth at low temperature and adjust it to needs for survival. The advantages of hardening to low temperature were very clearly expressed when the effects on O2 evolution and on the ...
NADPH:protochlorophyllide oxidoreductase (POR) catalyses the light-dependent reduction of protochlorophyllide to chlorophyllide, a key reaction in the chlorophyll biosynthetic pathway. To facilitate structure-function studies, POR from pea (Pisum sativum L.) has been overexpressed in Escherichia coli as a fusion with maltose-binding protein (MBP) at 5-10% of the total soluble cell protein. The ...
Glycollate oxidase (glycollate:oxygen oxidoreductase, EC 1.1.3.1) from Pisum .f>ativum has an unusual absorption spectrum which suggests that the flavin N(3)-H function of the FMN coenzyme is ionized at pH 8.3. The enzyme is reduced rapidly by the substrate glycollate to yield a normal, reduced FMN coenzyme which is readily reoxidized by Oz. No evidence for the occurrence of covalent intermedia...
