Substrate-specificity studies on protochlorophyllide reductase in barley (Hordeum vulgare) etioplast membranes.
1. The substrate specificity of the enzyme protochlorophyllide reductase in barley (Hordeum vulgare) etioplasts was investigated. 2. It was shown that naturally occurring esterified protochlorophyllide and chemically prepared protochlorophyllide methyl ester are not substrates for the enzyme, suggesting an important role for the C-7 carboxylic acid group in binding of the porphyrin to the enzym...
متن کاملIdentification of the Ndh (NAD(P)H-plastoquinone-oxidoreductase) complex in etioplast membranes of barley: changes during photomorphogenesis of chloroplasts.
In the last few years the presence in thylakoid membranes of chloroplasts of a NAD(P)H-plastoquinone oxidoreductase complex (Ndh complex) homologous to mitochondrial complex I has been well established. Herein, we report the identification of the Ndh complex in barley etioplast membranes. Two plastid DNA-encoded polypeptides of the Ndh complex (NDH-A and NDH-F) were relatively more abundant in ...
متن کاملFreeze-fracture analysis of thylakoid membranes and photosystem I and II enriched fractions from Phormidium laminosum.
Thylakoid membranes of the thermophilic cyanobacterium Phormidium laminosum have been fractionated into photosystem II and photosystem I particles. These fractions have been characterized by their partial electron transport activities, and biochemical and spectral properties. Exoplasmic fracture face and protoplasmic fracture face particles in the unfractionated thylakoid membranes were shown t...
متن کاملFreeze-fracture studies of photoreceptor membranes: new observations bearing upon the distribution of cholesterol
We performed electron microscopy of replicas from freeze-fractured retinas exposed during or after fixation to the cholesterol-binding antibiotic, filipin. We observed characteristic filipin-induced perturbations throughout the disk and plasma membranes of retinal rod outer segments of various species. It is evident that a prolonged exposure to filipin in fixative enhances rather than reduces p...
متن کاملACROSOMAL DISRUPTION IN SPERM Freeze-Fracture of Altered Membranes
"Capaci ta t ion" is a physiological event which alters sperm to permit rapid penetration through oocyte investments and fusion between gametes. Acrosomal "reaction," the physiological release of acrosomal contents, occurs after this facilitating process. In this study, acrosomal "disruption" of guinea pig and rat sperm was achieved in vitro by incubating sperm together with the follicular cont...
