Crystallization-induced asymmetric transformation of chiral-at-metal ruthenium(II) complexes bearing achiral ligands.

Chemistry (Weinheim an der Bergstrasse, Germany)

Hamelin O, Pécaut J, Fontecave M.
PMID: 15146526
Chemistry. 2004 May 17;10(10):2548-54. doi: 10.1002/chem.200305749.

Recently, we observed that the enantiopure Lambda form of the tributylammonium salt of the chiral anion tris[tetrachlorobenzene-1,2-bis(olato)]phosphate, also named Trisphat, was able to induce an efficient resolution of a Delta,Lambda racemic mixture of cis-[Ru(dmp)2(NCCH3)2](PF6)2 (dmp=2,9-dimethyl-1,10-phenanthroline) due to the spontaneous...

Catalytic asymmetric sulfoxidation by chiral manganese complexes: acetylacetonate anions as chirality switches.

Three manganese(II) complexes, namely [Mn(1)(ClO(4))(2)] (3), [Mn(1)(acac)(2)] (4), and [Mn(2)(1)(acac)(4)] (5), were isolated from solutions of Mn(ClO(4))(2) or Mn(acac)(2), and an easily accessible diimine ligand (1S,2S)-N,N'-bis-pyridin-2-ylmethylene-cyclohexane-1,2-diamine (1). Their structure was determined by X-ray crystallography, and these complexes proved to...

Examination of Gould's modified S1 (mS1) selective medium and Angle's non-selective medium for describing the diversity of Pseudomonas spp. in soil and root environments.

FEMS microbiology ecology

Tarnawski S, Hamelin J, Locatelli L, Aragno M, Fromin N.
PMID: 19719620
FEMS Microbiol Ecol. 2003 Jul 01;45(2):97-104. doi: 10.1016/S0168-6496(03)00130-2.

Abstract Studies on the diversity of environmental culturable Pseudomonas populations are dependent on the isolation procedure. This procedure includes the use of selective media which may influence the recovery of strains and thus the diversity described. In this study,...

Characterization of the surfaceome of the metal-reducing bacterium Desulfotomaculum reducens.

Frontiers in microbiology

Dalla Vecchia E, Shao PP, Suvorova E, Chiappe D, Hamelin R, Bernier-Latmani R.

Front Microbiol. 2014 Aug 19;5:432. doi: 10.3389/fmicb.2014.00432. eCollection 2014.

Desulfotomaculum reducens strain MI-1 is a Gram-positive, sulfate-reducing bacterium also capable of reducing Fe(III). Metal reduction in Gram-positive bacteria is poorly understood. Here, we investigated Fe(III) reduction with lactate, a non-fermentable substrate, as the electron donor. Lactate consumption is...

Mitochondrial roles and cytoprotection in chronic liver injury.

Biochemistry research international

Degli Esposti D, Hamelin J, Bosselut N, Saffroy R, Sebagh M, Pommier A, Martel C, Lemoine A.

Biochem Res Int. 2012;2012:387626. doi: 10.1155/2012/387626. Epub 2012 Jun 15.

The liver is one of the richest organs in terms of number and density of mitochondria. Most chronic liver diseases are associated with the accumulation of damaged mitochondria. Hepatic mitochondria have unique features compared to other organs' mitochondria, since...

The Membrane-Bound C Subunit of Reductive Dehalogenases: Topology Analysis and Reconstitution of the FMN-Binding Domain of PceC.

Frontiers in microbiology

Buttet GF, Willemin MS, Hamelin R, Rupakula A, Maillard J.

Front Microbiol. 2018 Apr 24;9:755. doi: 10.3389/fmicb.2018.00755. eCollection 2018.

Organohalide respiration (OHR) is the energy metabolism of anaerobic bacteria able to use halogenated organic compounds as terminal electron acceptors. While the terminal enzymes in OHR, so-called reductive dehalogenases, are well-characterized, the identity of proteins potentially involved in electron...

The membrane-anchored Src tyrosine kinase is involved in numerous pathways and its deregulation is involved in human cancer. Our knowledge on Src regulation relies on crystallography, which revealed intramolecular interactions to control active Src conformations. However, Src contains a...
