Reduction of ferredoxin:thioredoxin reductase by artificial electron donors.

Photosynthesis research

Schürmann P, Stritt-Etter AL, Li J.
PMID: 24301597
Photosynth Res. 1995 Nov;46(1):309-12. doi: 10.1007/BF00020445.

The ferredoxin:thioredoxin reductase is an essential enzyme of the light dependent regulatory system in oxygenic photosynthesis. It is composed of two dissimilar subunits and contains a 4Fe-4S cluster and a redox-active disulfide bridge. Artificial electron donors of redox potentials...

Ring Finger Protein 11 Inhibits Melanocortin 3 and 4 Receptor Signaling.

Frontiers in endocrinology

Müller A, Niederstadt L, Jonas W, Yi CX, Meyer F, Wiedmer P, Fischer J, Grötzinger C, Schürmann A, Tschöp M, Kleinau G, Grüters A, Krude H, Biebermann H.

Front Endocrinol (Lausanne). 2016 Aug 08;7:109. doi: 10.3389/fendo.2016.00109. eCollection 2016.

Intact melanocortin signaling via the G protein-coupled receptors (GPCRs), melanocortin receptor 4 (MC4R), and melanocortin receptor 3 (MC3R) is crucial for body weight maintenance. So far, no connection between melanocortin signaling and hypothalamic inflammation has been reported. Using a...

A dicistronic construct for the expression of functional spinach chloroplast ferredoxin:thioredoxin reductase in Escherichia coli.

Plant science : an international journal of experimental plant biology

Gaymard E, Franchini L, Manieri W, Stutz E, Schürmann P.
PMID: 10996250
Plant Sci. 2000 Sep 08;158(1):107-113. doi: 10.1016/s0168-9452(00)00310-1.

Ferredoxin:thioredoxin reductase (FTR) is a heterodimeric Fe&z.sbnd;S containing disulfide reductase involved in the light-dependent activation of photosynthetic enzymes. We have designed a dicistronic construct for the heterologous expression of this nucleus encoded chloroplast protein in Escherichia coli. The coding...

Local atomic environment of Si suboxides at the SiO2/Si(111) interface determined by angle-scanned photoelectron diffraction.

Physical review letters

Dreiner S, Schürmann M, Westphal C, Zacharias H.
PMID: 11328097
Phys Rev Lett. 2001 Apr 30;86(18):4068-71. doi: 10.1103/PhysRevLett.86.4068.

Local environments of Si suboxides at the interface between a thermally grown SiO2 film and Si(111) were studied by angle-scanned photoelectron diffraction. Si 2p core-level spectra containing chemically shifted components were recorded. The components were deconvoluted by least squares...

VTE Risk assessment - a prognostic Model: BATER Cohort Study of young women.

Thrombosis journal

Heinemann LA, Dominh T, Assmann A, Schramm W, Schürmann R, Hilpert J, Spannagl M.
PMID: 15836797
Thromb J. 2005 Apr 18;3(1):5. doi: 10.1186/1477-9560-3-5.

BACKGROUND: Community-based cohort studies are not available that evaluated the predictive power of both clinical and genetic risk factors for venous thromboembolism (VTE). There is, however, clinical need to forecast the likelihood of future occurrence of VTE, at least...

Effect of powdery mildew infection on photosynthesis by leaves and chloroplasts of sugar beets.

Plant physiology

Magyarosy AC, Schürmann P, Buchanan BB.
PMID: 16659511
Plant Physiol. 1976 Apr;57(4):486-9. doi: 10.1104/pp.57.4.486.

Chloroplasts isolated from powdery mildew-infected (Erysiphe polygoni DC) sugar beet leaves (Beta vulgaris L) showed a reduction in the rate of electron transport and in the accompanying ATP formation in noncyclic photophosphorylation (water as electron donor, NADP as electron...

Characterization of the regulatory function of the 46-kDa isoform of Rubisco activase from Arabidopsis.

Photosynthesis research

Zhang N, Schürmann P, Portis AR.
PMID: 16228326
Photosynth Res. 2001;68(1):29-37. doi: 10.1023/A:1011845506196.

Arabidopsis Rubisco activase was recently shown to be regulated by redox changes in the larger (46-kDa) isoform specifically mediated by thioredoxin-f [Zhang and Portis (1999) Proc Natl Acad Sci USA 96: 9438-9443]. Reduction greatly increases the activity of the...

Proteomics uncovers proteins interacting electrostatically with thioredoxin in chloroplasts.

Photosynthesis research

Balmer Y, Koller A, Val GD, Schürmann P, Buchanan BB.

The ability of thioredoxin f to form an electrostatic (non-covalent) complex, earlier found with fructose-1,6-bisphosphatase, was extended to include 27 previously unrecognized proteins functional in 11 processes of chloroplasts. The proteins were identified by combining thioredoxin f affinity chromatography...
