Thermodynamic bounds on the ultra- and infra-affinity of Hsp70 for its substrates [PDF]

, 2017
The 70 kDa Heat Shock Proteins Hsp70 have several essential functions in living systems, such as protecting cells against protein aggregation, assisting protein folding, remodeling protein complexes and driving the translocation into organelles.

Cooperativity in ATP hydrolysis by GroEL is increased by GroES [PDF]

FEBS Letters, 1991
The kinetics of ATP hydrolysis by the ‘molecular chaperone’ GroEL and the inhibition of this hydrolysis by GroES have been studied in more detail. It is shown that the hydrolysis of ATP by GroEL is cooperative with respect to ATP with a Hill coefficient of 1.86 (±0.13).

Analysis of the regulation of undecaprenyl diphosphate dephosphorylation in Escherichia coli

FEBS Open Bio, EarlyView.
BacA, PgpB, and YbjG phosphatases are involved in undecaprenyl phosphate (C55P) synthesis in Escherichia coli. We analyzed the lipid contents and the gene expression in the gene‐disruption strains. Undecaprenyl diphosphate (C55PP) level increased in the bacA, ybjG double‐disruption strain, but C55P levels were similar in all strains.

A two-state model for helicase translocation and unwinding of nucleic acids [PDF]

, 2008
Helicases are molecular motors that unwind double-stranded nucleic acids (dsNA), such as DNA and RNA). Typically a helicase translocates along one of the NA single strands while unwinding and uses adenosine triphosphate (ATP) hydrolysis as an energy ...

Preparation and characterization of renal cell peptides from fetal rats for their antitumor activity

FEBS Open Bio, EarlyView.
This study aimed to prepare renal cells (RCs) from fetal rats which were digested by enzymes. Candidate peptides RCPs were characterized by capillary HPLC and MS and their bioactivity was predicted using peptideranker. The predicted top 10 bioactive peptides were synthesized.

Structure insights into mechanisms of ATP hydrolysis and the activation of human heat-shock protein 90.

Acta Biochimica et Biophysica Sinica, 2012
The activation of molecular chaperone heat-shock protein 90 (Hsp90) is dependent on ATP binding and hydrolysis, which occurs in the N-terminal domains of protein.

Actin dynamics controlled by IqgC, a RasGAP at the crossroads between the IQGAP and fungal GAP1 families

FEBS Open Bio, EarlyView.
IqgC is a RasGAP from Dictyostelium discoideum. IqgC binds RasG via its RasGAP domain and deactivates it on macroendocytic cups, thereby suppressing the uptake of fluid and particles. IqgC has a positive effect on cell‐substratum adhesion, and its RGCt domain is required for recruitment to ventral foci.

Quantum and classical dynamics simulations of ATP hydrolysis in solution.

Journal of Chemical Theory and Computation, 2012
ATP hydrolysis is a key reaction in living cells that drives many cellular processes. The reaction, which involves gamma phosphate cleavage from ATP, converting it to ADP, has been suggested to occur via an associative or dissociative mechanism dependent

Comprehensive structural model of the mechanochemical cycle of a mitotic motor highlights molecular adaptations in the kinesin family [PDF]

, 2014
Kinesins are responsible for a wide variety of microtubule-based, ATP-dependent functions. Their motor domain drives these activities but the molecular adaptations that specify these diverse and essential cellular activities are poorly understood.

BCS1L‐Associated Disease: 5′‐UTR Variant Shifts the Phenotype Towards Axonal Neuropathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives To investigate the consequences of a pathogenic missense variant (c.838C>T; p.L280F) and a 5′‐UTR regulatory variant (c.‐122G>T) in BCS1L on disease pathogenesis and to understand how regulatory variants influence disease severity and clinical presentation.
