Kinetics and regulation of the myofibrillar adenosine triphosphatase [PDF]
Biochemical Journal, 1978 1. The steady-state kinetic behaviour of the ATPase (adenosine triphosphatase) of intact myofibrils was studied in the presence of both high and low concentrations of Ca2+ (0.25 mM and less than 10 nM respectively). 2. Kinetic data were collected over the initial linear phase of the assay, which lasts for 20–60s.

36 degree step size of proton-driven c-ring rotation in FoF1-ATP synthase [PDF]
, 2009 Synthesis of the biological "energy currency molecule" adenosine triphosphate ATP is accomplished by FoF1-ATP synthase. In the plasma membrane of Escherichia coli, proton-driven rotation of a ring of 10 c subunits in the Fo motor powers catalysis in the ...

Altered chemomechanical coupling causes impaired motility of the kinesin-4 motors KIF27 and KIF7. [PDF]
, 2018 Kinesin-4 motors play important roles in cell division, microtubule organization, and signaling. Understanding how motors perform their functions requires an understanding of their mechanochemical and motility properties.

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

Modulation of the asymmetry of sea urchin sperm flagellar bending by calmodulin [PDF]
, 1985 Sea urchin spermatozoa demembranated with Triton X-100 in the presence of EGTA, termed potentially asymmetric, generate asymmetric bending waves in reactivation solutions containing EGTA. After they are converted to the potentially symmetric condition by

Exploring Immediate Photon Effects From 635 nm Light on Mitochondrial Bioenergetics
Journal of Biophotonics, EarlyView.The investigation of in vitro impacts of 635 nm laser irradiation in mitochondrial bioenergetics demonstrated that red light induces transient and localized effects, highlighting the complexities of cellular and mitochondrial photostimulation mechanisms. ABSTRACT Visible light primarily targets mitochondria at the cellular level, but photon interaction
