Autor: Lasse Evensen, David R Micklem, Anna Blois, Sissel Vik Berge, Niels Aarsaether, Amanda Littlewood-Evans, Jeanette Wood, James B Lorens

Publikováno v: PLoS ONE, Vol 4, Iss 6, p e5798 (2009)

BACKGROUND: Blood vessels comprise endothelial cells, mural cells (pericytes/vascular smooth muscle cells) and basement membrane. During angiogenesis, mural cells are recruited to sprouting endothelial cells and define a stabilizing context, comprisi

Use of Surface Plasmon Resonance for Real-Time Measurements of the Global Conformational Transition in Human Phenylalanine Hydroxylase in Response to Substrate Binding and Catalytic Activation

Autor: Sissel Vik Berge, Torgeir Flatmark, Anne Jorunn Stokka

Publikováno v: Analytical Biochemistry. 294:95-101

In the present study the optical biosensor technique, based on the surface plasmon resonance (SPR) phenomenon, was used for real-time measurements of the reversible binding of the pterin cofactor (6R)-l-erythro-5,6,7,8-tetrahydrobiopterin (BH(4)) and

Kinetic studies of tetrameric recombinant human tyrosine hydroxylase isoform 1 (hTH1) have revealed properties so far not reported for this enzyme. Firstly, with the natural cofactor (6R)-Lerythro-5,6,7, 8-tetrahydrobiopterin (H4biopterin) a time-dep

The assignment of the Ca2+-ATPase activity of chromaffin granules to the proton translocating ATPase

Autor: Sissel Vik Berge, Martin Grønberg, Eystein S. Husebye, Torgeir Flatmark

Publikováno v: FEBS Letters. (1):25-30

CaATP is shown to function as a substrate for the proton translocating ATPase of chromaffin granule ghosts at concentrations which are comparable to that of MgATP. Using the initial rate of the proton pump activity as the measure (ΔpH/Δt), an appar

Inhibition of N-ethylmaleimide of the MgATP-driven proton pump of the chromaffin granules

Autor: Torgeir Flatmark, Sissel Vik Berge, Eystein S. Husebye, Martin Grønberg

Publikováno v: FEBS letters. 149(1)

The thiol reagent N-ethylmaleimide (NEM) completely inhibits the proton pump activity of the H+-ATPase in chromaffin granule 'ghosts' at concentrations which only partly (approximately 20%) inhibit the Mg2+-dependent ATP hydrolysis. Half-maximal inhi
