The Targeting of the atToc159 Preprotein Receptor to the Chloroplast Outer Membrane is Mediated by its GTPase Domain and is Regulated by GTP [PDF]

open access: yes, 2002
The multimeric translocon at the outer envelope membrane of chloroplasts (Toc) initiates the recognition and import of nuclear-encoded preproteins into chloroplasts.

All‐Cellulose‐Based Photonic Glitters

open access: yesAdvanced Functional Materials, EarlyView.
Uniform, disc‐shaped photonic CNC glitters with adjustable structural colors and diameters are fabricated on hydrophilic ethyl cellulose films using electrospray deposition. By employing patterned ethyl cellulose films with pre‐designed hydrophilic regions, photonic patterns can be created with these all‐cellulose‐based glitters, demonstrating their ...

The ancestral role of ATP hydrolysis in type II topoisomerases: prevention of DNA double-strand breaks

open access: yesNucleic Acids Research, 2011
Type II DNA topoisomerases (topos) catalyse changes in DNA topology by passing one double-stranded DNA segment through another. This reaction is essential to processes such as replication and transcription, but carries with it the inherent danger of ...

Evidence That the P\u3csub\u3ei\u3c/sub\u3e Release Event Is the Rate-Limiting Step in the Nitrogenase Catalytic Cycle [PDF]

open access: yes, 2016
Nitrogenase reduction of dinitrogen (N2) to ammonia (NH3) involves a sequence of events that occur upon the transient association of the reduced Fe protein containing two ATP molecules with the MoFe protein that includes electron transfer, ATP hydrolysis,

Monitoring enzymatic ATP hydrolysis by EPR spectroscopy

open access: yesChem. Commun., 2014
Adenosine triphosphate is modified with two nitroxide radicals and employed to demonstrate that electron paramagnetic resonance spectroscopy can be used to study the enzymatic hydrolysis of doubly labelled substrate analogues.

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery

open access: yesAdvanced Functional Materials, EarlyView.
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

Asymmetry of movements in CFTR's two ATP sites during pore opening serves their distinct functions

open access: yeseLife, 2017
CFTR, the chloride channel mutated in cystic fibrosis (CF) patients, is opened by ATP binding to two cytosolic nucleotide binding domains (NBDs), but pore-domain mutations may also impair gating.

A remote response of ATP hydrolysis

open access: yes, 2013
ATP-hydrolysis is the basic energy source of many physiological processes, but there is a lack of knowledge regarding its biological role other than energy transfer and thermogenesis. Not all the energy released by ATP-hydrolysis could be used in powering target biological processes and functions. Partial energy dissipates into water. By validating the

The rate constant for ATP hydrolysis by polymerized actin

open access: yesFEBS Letters, 1984
Polymerized actin hydrolyzes bound ATP in a reaction that depends on the concentration of polymerized ATP‐actin, not on the rate of incorporation of ATP‐actin into the polymer. The apparent first order rate constant is about 0.07 s−1 at 21°C in 50 mM KCl with 1 mM MgCl2 or CaCl2.
