On the kinetic and allosteric regulatory properties of the ADP-glucose pyrophosphorylase from Rhodococcus jostii: An approach to evaluate glycogen metabolism in oleaginous bacteria [PDF]

open access: yes, 2016
Rhodococcus spp. are oleaginous bacteria that accumulate glycogen during exponential growth. Despite the importance of these microorganisms in biotechnology, little is known about the regulation of carbon and energy storage, mainly the relationship ...

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 ...

Cold-Water Immersion Promotes Antioxidant Enzyme Activation in Elite Taekwondo Athletes

open access: yesApplied Sciences, 2021
The aim of this study was to investigate the effect of cold-water immersion (CWI) on lipid peroxides and antioxidant enzymes in adult Taekwondo athletes after a match. A cross-sectional study was performed.

Interactions between the endocrine and immune systems in locusts [PDF]

open access: yes, 2003
The prophenoloxidase cascade in the haemolymph of mature adult Locusta migratoria migratorioides (R & F) is activated in response to injection of laminarin, a -1,3 glucan.

Genome-scale architecture of small molecule regulatory networks and the fundamental trade-off between regulation and enzymatic activity [PDF]

open access: yes, 2017
Metabolic flux is in part regulated by endogenous small molecules that modulate the catalytic activity of an enzyme, e.g., allosteric inhibition. In contrast to transcriptional regulation of enzymes, technical limitations have hindered the production of ...

A survey of orphan enzyme activities [PDF]

open access: yesBMC Bioinformatics, 2007
Using computational database searches, we have demonstrated previously that no gene sequences could be found for at least 36% of enzyme activities that have been assigned an Enzyme Commission number. Here we present a follow-up literature-based survey involving a statistically significant sample of such "orphan" activities.

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 ...

Unraveling the activation mechanism of the potato tuber ADP-glucose pyrophosphorylase. [PDF]

open access: yesPLoS ONE, 2013
ADP-glucose pyrophosphorylase regulates the synthesis of glycogen in bacteria and of starch in plants. The enzyme from plants is mainly activated by 3-phosphoglycerate and is a heterotetramer comprising two small and two large subunits.

Synergistic recruitment of UbcH7~Ub and phosphorylated Ubl domain triggers parkin activation [PDF]

open access: yes, 2018
The E3 ligase parkin ubiquitinates outer mitochondrial membrane proteins during oxidative stress and is linked to early-onset Parkinson’s disease. Parkin is autoinhibited but is activated by the kinase PINK1 that phosphorylates ubiquitin leading to ...

Determination of enzyme activities with the enzyme thermistor unit [PDF]

open access: yesFEBS Letters, 1979
Practically all enzyrnic reactions can be followed by calorimetry. Important advantages of this technique are that the optical properties of the sample do not interfere with the measurements and that no auxiliary enzymic reactions are required such as those leading to changes in optical absorption that can be followed spectrophotometrically.
