ADENOSINE TRIPHOSPHATASE LOCALIZATION IN AMPHIBIAN EPIDERMIS [PDF]

open access: yesThe Journal of Cell Biology, 1966
The localization of ATPase1 activity has been studied by light and electron microscopy in the epidermis of Rana pipiens, Rana catesbiana, and Bufo marinus. The reaction was carried out on skin (glutaraldehyde-fixed or fresh) sectioned with or without freezing. Best results were obtained with nonfrozen sections of fixed tissue.

ADENOSINE TRIPHOSPHATASE IN THE MITOTIC APPARATUS [PDF]

open access: yesProceedings of the National Academy of Sciences, 1961
Methods.-Isolation of the mitotic apparatus: The principle of the new method has been described in several publications, and a detailed account of the procedure will appear shortly.5 Sea urchin eggs (Stronglycentrotus purpuratus) are the source of material, providing large quantities of cells in synchronous division.

Effect in vitro of the Phenobarbital on the Activity of the Enzyme Adenosine Triphosphatase (ATPase) of Sodium and Potassium Dependent in Human Placenta.

open access: yesMedisur, 2007
Background: Most of the drugs can pass to the fetus through the placenta, conditioning alterations of the development and fetal growth. Objective: To evaluate the effect in vitro of Phenobarbital on the activity of adenosine triphosphatase of sodium and ...

The emerging role of E3 ubiquitin ligase RNF213 as an antimicrobial host determinant

open access: yesFrontiers in Cellular and Infection Microbiology, 2023
Ring finger protein 213 (RNF213) is a large E3 ubiquitin ligase with a molecular weight of 591 kDa that is associated with moyamoya disease, a rare cerebrovascular disease. It is located in the cytosol and perinuclear space.

LEAD-ADENOSINE TRIPHOSPHATE COMPLEXES IN ADENOSINE TRIPHOSPHATASE HISTOCHEMISTRY [PDF]

open access: yesJournal of Histochemistry & Cytochemistry, 1969
Chelation of lead by adenosine triphosphate (ATP) and its consequences for adenosine triphosphatase histochemistry were examined. The formation constant of lead-ATP chelates was found by two methods to be 4.6-4.7 x 104. The characteristics of enzyme inhibition by lead were consistent with the predicted effects of lead-ATP chelation.

FLAGELLAR MOVEMENT AND ADENOSINE TRIPHOSPHATASE ACTIVITY IN SEA URCHIN SPERM EXTRACTED WITH TRITON X-100

open access: yesJournal of Cell Biology, 1972
Extraction with 0 04% (w/v) Triton X-100 removes the flagellar membrane from sea urchin sperm while leaving the motile apparatus apparently intact When reactivated in a suitable medium containing exogenous adenosine triphosphate (ATP), nearly 100% of the

Adenosine signaling in tumor-associated macrophages and targeting adenosine signaling for cancer therapy

open access: yesCancer Biology & Medicine
This review examined the critical role of adenosine signaling in modulating the behavior of tumor-associated macrophages (TAMs), a key determinant of the tumor microenvironment (TME).

Lipophosphoglycan 3 From Binds Heparin With Micromolar Affinity

open access: yesBioinformatics and Biology Insights, 2018
Leishmania infantum chagasi is an intracellular protozoan parasite responsible for visceral leishmaniasis, a fatal disease in humans. Heparin-binding proteins (HBPs) are proteins that bind to carbohydrates present in glycoproteins or glycolipids ...

Flexibility of an Active Center in Sodium-Plus-Potassium Adenosine Triphosphatase

open access: yesThe Journal of General Physiology, 1969
In plasma membranes of intact cells an enzymatic pump actively transports sodium ions inward and potassium ions outward. In preparations of broken membranes it appears as an adenosine triphosphatase dependent on magnesium, sodium, and potassium ions ...
