Extremophiles are organisms which inhabit environments characterized by properties harsh enough to hinder the survival of common cells. They are highly diversified and are classified on the basis of the main extreme property that prevails in the habi

Pregnancy rates after transfer of embryos obtained from different stimulation protocols and frozen at either pronucleate or multicellular stages

Autor: Caroline Jouan, C. Gerday, A. Demoulin, Michel Dubois

Publikováno v: Human Reproduction. 6:799-804

After in-vitro fertilization, 2161 supernumerary embryos were frozen with 1,2-propanediol and sucrose as cryoprotectants at either pronucleate or multicellular (2-6 blastomeres) stages. By the end of March 1990, 494 pronucleate stage embryos and 492

[Group B streptococcus in the antenatal clinic and in the delivery room: a matter of systematic attitude]

Autor: S, Lorquet, P, Melin, J M, Minon, M, Carpentier, C, Gerday, J, Rigo, J M, Foidart

Publikováno v: Journal de gynecologie, obstetrique et biologie de la reproduction. 34(2)

We wanted to evaluate the compliance to the local recommendations, similar to the CDC (Centers for Disease Control and prevention) recommendations launched in 1996, for the prevention of perinatal group B streptococcal (GBS) disease in the clinical p

A perspective on cold enzymes: current knowledge and frequently asked questions

Autor: J C, Marx, V, Blaise, T, Collins, S, D'Amico, D, Delille, E, Gratia, A, Hoyoux, A L, Huston, G, Sonan, G, Feller, C, Gerday

Publikováno v: Cellular and molecular biology (Noisy-le-Grand, France). 50(5)

Studies on psychrophilic enzymes to determine the structural features important for cold-activity have attracted increased attention in the last few years. This enhanced interest is due to the attractive properties of such proteins, i.e. a high speci

A DNA ligase from the psychrophile Pseudoalteromonas haloplanktis gives insights into the adaptation of proteins to low temperatures

Autor: D, Georlette, Z O, Jónsson, F, Van Petegem, J, Chessa, J, Van Beeumen, U, Hübscher, C, Gerday

Publikováno v: European journal of biochemistry. 267(12)

The cloning, overexpression and characterization of a cold-adapted DNA ligase from the Antarctic sea water bacterium Pseudoalteromonas haloplanktis are described. Protein sequence analysis revealed that the cold-adapted Ph DNA ligase shows a signific

Purification and characterization of the heat-labile alpha-amylase secreted by the psychrophilic bacterium TAC 240B

Autor: J P, Chessa, G, Feller, C, Gerday

Publikováno v: Canadian journal of microbiology. 45(6)

A total of 59 bacteria samples from Antarctic sea water were collected and screened for their ability to produce alpha-amylase. The highest activity was recorded from an isolate identified as an Alteromonas species. The purified alpha-amylase shows a

Thermodynamic stability of a cold-active alpha-amylase from the Antarctic bacterium Alteromonas haloplanctis

Autor: G, Feller, D, d'Amico, C, Gerday

Publikováno v: Biochemistry. 38(14)

The thermal stability of the cold-active alpha-amylase (AHA) secreted by the Antarctic bacterium Alteromonas haloplanctis has been investigated by intrinsic fluorescence, circular dichroism, and differential scanning calorimetry. It was found that th

Crystallization and preliminary X-ray diffraction studies of alpha-amylase from the antarctic psychrophile Alteromonas haloplanctis A23

Autor: N, Aghajari, G, Feller, C, Gerday, R, Haser

Publikováno v: Protein science : a publication of the Protein Society. 5(10)

A cold-active alpha-amylase was purified from culture supernatants of the antarctic psychrophile Alteromonas haloplanctis A23 grown at 4 degrees C. In order to contribute to the understanding of the molecular basis of cold adaptations, crystallograph
