Adenosine Triphosphatase Activities of Muscle Sarcolemma

Journal of Biological Chemistry, 1973
Abstract Isolated sarcolemma hydrolyzed ATP in the presence of Mg2+ and Ca2+. MgATPase was stimulated by low concentrations of Ca2+ and inhibited by high concentrations of this cation. Membranes hydrolyzed p-nitrophenylphosphate in the presence of Mg2+; this activity was stimulated by Ca2+ and K+.

Plant‐derived vesicle‐like nanoparticles in food crops: emerging insights into nutritional biofortification and biomedical applications

Plant Biotechnology Journal, Volume 23, Issue 8, Page 3260-3282, August 2025.
Summary Food crops, as the cornerstone of human nutrition, not only provide essential macronutrients but also encompass a rich spectrum of bioactive compounds that promote health. Of particular significance are underutilized minor crops, which contain unique beneficial components with proven nutraceutical properties. These valuable bioactive components

Mutation of CD2AP and SH3KBP1 binding motif in alphavirus nsP3 hypervariable domain results in attenuated virus [PDF]

, 2018
Infection by Chikungunya virus (CHIKV) of the Old World alphaviruses (family Togaviridae) in humans can cause arthritis and arthralgia. The virus encodes four non-structural proteins (nsP) (nsP1, nsp2, nsP3 and nsP4) that act as subunits of the virus ...

A study of the effects of substrate concentration and certain relaxing factors on the magnesium-activated myofibrillar adenosine triphosphatase.

Biochemical Journal, 1956
Marsh (1952) first showed that whereas the apparent rate of hydrolysis of adenosine triphosphate (ATP) by homogenates of fresh rabbit muscle in an isotonic solution of potassium chloride was comparatively low, after centrifuging and removal of the ...

Recent advances in the structure, function and regulation of the volume‐regulated anion channels and their role in immunity

The Journal of Physiology, Volume 603, Issue 15, Page 4255-4291, 1 August 2025.
Abstract figure legend The volume‐regulated anion channel (VRAC), composed of leucine‐rich repeat‐containing 8 (LRRC8) proteins, serves both canonical and non‐canonical functions in vertebrate cells. The canonical function of this channel relates to its original description, which is homeostatic regulation of cell volume in response to hypotonic ...

Plasmodium RNA triphosphatase validation as antimalarial target

International Journal for Parasitology: Drugs and Drug Resistance
Target-based approaches have traditionally been used in the search for new anti-infective molecules. Target selection process, a critical step in Drug Discovery, identifies targets that are essential to establish or maintain the infection, tractable to ...
