Enzyme activity and flexibility at very low hydration [PDF]

open access: yes, 2005
Recent measurements have demonstrated enzyme activity at hydrations as low as 3%. This raises the question of whether hydration-induced enzyme flexibility is important for activity. Here, to address this, picosecond dynamic neutron scattering experiments

The structural basis of the multi-step allosteric activation of Aurora B kinase

open access: yeseLife, 2023
Aurora B, together with IN-box, the C-terminal part of INCENP, forms an enzymatic complex that ensures faithful cell division. The [Aurora B/IN-box] complex is activated by autophosphorylation in the Aurora B activation loop and in IN-box, but it is not ...

Structural Basis for the Differential Regulatory Roles of the PDZ Domain in C-Terminal Processing Proteases

open access: yesmBio, 2019
Carboxyl (C)-terminal processing proteases (CTPs) participate in protective and regulatory proteolysis in bacteria. The PDZ domain is central to the activity of CTPs but plays inherently different regulatory roles.

Enzyme activities in activated sludge flocs [PDF]

open access: yesApplied Microbiology and Biotechnology, 2007
This study quantified the activities of enzymes in extracellular polymeric substances (EPS) and in pellets. Seven commonly adopted extraction schemes were utilized to extract from aerobic flocs the contained EPS, which were further categorized into loosely bound (LB) and tightly bound (TB) fractions.

Enzyme-mediated hydrolytic activation of prodrugs

open access: yesActa Pharmaceutica Sinica B, 2011
Prodrug design is an important part of drug discovery. Prodrugs can offer many advantages over parent drugs such as increased solubility, enhanced stability, improved bioavailability, reduced side effects, and better selectivity.

In vivo activation of methyl-coenzyme M reductase by carbon monoxide

open access: yesFrontiers in Microbiology, 2013
Methyl-coenzyme M reductase (MCR) from methanogenic archaea catalyzes the rate-limiting and final step in methane biosynthesis. Using coenzyme B (CoBSH) as the two-electron donor, MCR reduces methyl-coenzyme M (CH3-SCoM) to methane and the mixed ...

Pró-fármaco ativado por enzima, uma estratégia promissora na quimioterapia

open access: yesQuímica Nova, 2006
Strategies that promote selective activation of prodrugs by enzymes can be divided into two major classes: 1) deliver of a monoclonal antibody-enzyme immunoconjugate that can recognize a specific antigen and promote the prodrug to a citotoxic drug, with ...
