Activation of the Bradykinin System by Angiotensin-Converting Enzyme Inhibitors

open access: yesEuropean Journal of Inflammation, 2010
The Bradykinin (BK) system has a very significant role in the regulation of blood pressure (BP). Hence, reduced activity of BK receptors mediated via decreased circulating endogenous kinin might explain the cause of high BP.

Subcellular localization of hexadecanedioic acid activation in human liver

open access: yesJournal of Lipid Research, 1974
The activation of hexadecanedioic acid has been studied in subcellular fractions of human liver. The activation capacity in a total homogenate of human liver was found to be 0.5 μmole/min/g wet wt of tissue, about 10% of that for palmitic acid ...

Cofilin activation in pancreatic acinar cells plays a pivotal convergent role for mediating CCK-stimulated enzyme secretion and growth

open access: yesFrontiers in Physiology, 2023
Introduction: The actin regulatory protein, cofilin plays a key signaling role in many cells for numerous cellular responses including in proliferation, development, motility, migration, secretion and growth.

β-Galactosidase- and Photo-Activatable Fluorescent Probes for Protein Labeling and Super-Resolution STED Microscopy in Living Cells

open access: yesMolecules
We report on the synthesis of two fluorescent probes which can be activated by β-Galactosidase (β-Gal) enzymes and/or light. The probes contained 2-nitro-4-oxybenzyl and 3-nitro-4-oxybenzyl fragments, with β-Gal residues linked to C-4.

Covalent immobilization of glucoamylase enzyme onto chemically activated surface of κ-carrageenan

open access: yesBulletin of the National Research Centre, 2019
Background Glucoamylase enzyme is one of the most important enzymes. It catalyzes the hydrolysis of starch into soluble sugars. It was covalently immobilized onto κ-carrageenan gel beads after activation by using polyethylenimine (PEI) followed by ...

Ack1: activation and regulation by allostery. [PDF]

open access: yesPLoS ONE, 2013
The non-receptor tyrosine kinase Ack1 belongs to a unique multi-domain protein kinase family, Ack. Ack is the only family of SH3 domain containing kinases to have an SH3 domain following the kinase domain; others have their SH3 domains preceding the ...

Vicinal glutamates are better phosphomimetics: Phosphorylation is required for allosteric activation of guanylyl cyclase-A

open access: yesFrontiers in Molecular Neuroscience, 2022
Multisite phosphorylation of guanylyl cyclase (GC)-A, also known as NPR-A or NPR1, is required for receptor activation by natriuretic peptides (NPs) because alanine substitutions for the first four GC-A phosphorylation sites produce an enzyme that cannot

Cysteine 904 is required for maximal insulin degrading enzyme activity and polyanion activation.

open access: yesPLoS ONE, 2012
Cysteine residues in insulin degrading enzyme have been reported as non-critical for its activity. We found that converting the twelve cysteine residues in rat insulin degrading enzyme (IDE) to serines resulted in a cysteine-free form of the enzyme with ...

Kinetic steps for the hydrolysis of sphingomyelin by Bacillus cereus sphingomyelinase in lipid monolayers

open access: yesJournal of Lipid Research, 2000
The sphingomyelinase (Sphmase) activity degrading sphingomyelin (Sphm) monolayers shows a slow-reaction latency period before exhibiting constant rate catalysis. These two kinetic regions are regulated independently by the lateral surface pressure and by
