How do proteins evolve and function ?

ITHACA, N.Y. — Cornell University researchers, who are trying to understand how proteins evolve and function by looking at their structural features, have uncovered the crystal structure of a protein involved in making the building blocks of DNA correctly.


The protein is AIRs kinase, and to the researchers’ surprise, its shape is similar to other members of the riboside kinase family, proteins that are important in making DNA and RNA, the molecules that make up genes. As a result, the research group now has nine members of the riboside kinase family that are thought to have evolved from a common protein ancestor.


Writing in a recent issue of the journal Structure , Steven Ealick, professor of chemistry and chemical biology, and his graduate student Yan Zhang report that revealing the structure of AIRs kinase is another step in deciphering what proteins look like, a major goal of the National Institutes of Health, which funds the Ealick research group’s work.


“Often, two proteins with the same function have no sequence similarity,” says Ealick, whose research group works with crystallized proteins, the building blocks of all living organisms, and has solved 50 protein structures over the past 20 years. “From knowing the genetic sequence alone, we wouldn’t necessarily guess that two proteins play a similar role in an organism.”

Clariant set to beat Q3 FY 03 sales forecast

Clariant expects to beat ’03 operating results this year, helped by cost cuts and rising demand in most of its markets, the specialty chemicals firm said on Tuesday, as it reported solid growth in third-quarter sales.

The maker of pigments used to colour everything from jeans to cars said it expected ’04 continuing sales and operating income — excluding restructuring costs — above last year’s levels, underlining the effects of a sector recovery and its restructuring programme.

In the third quarter alone, operating profit came in at a lower-than-expected 130m Swiss francs ($109m) from a restated 135m a year ago, even though analysts said the core units appeared to be on track.

100 000 Euro für teutolabs Chemie

Seit der Gründung des teutolabs CHEMIE im Jahr 2000, dem dann die Labors für Physik und Mathematik folgten, haben mehr als 12 000 Kinder und Jugendliche die Möglichkeit genutzt, in der Universität Bielefeld unter fachkundiger Anleitung naturwissenschaftliche und mathematische Experimente durchzuführen. Die Resonanz ist so groß, dass die interessierten Schulklassen erhebliche Wartezeiten einkalkulieren müssen. Für die Chemie existiert daher inzwischen ein Netzwerk mit kleinen “Filialen” des Uni-teutolabs an zahlreichen Schulen. Darüber hinaus finden in diesem Fach inzwischen in großem Umfang Lehrerfortbildungen zur anschaulichen Gestaltung des naturwissenschaftlichen Unterrichts statt. Eine enge Verflechtung mit Schulen der Region ergibt sich durch die Teilabordnung von Lehrern, die den Laborbetrieb (gerade hinsichtlich der didaktischen Aufbereitung) wesentlich mitbestimmen. Zahlreiche studentische Hilfskräfte - oft Lehramtsstudierende - vervollständigen die Labor-Teams und können dabei wertvolle Erfahrungen im Umgang mit Schülern sammeln. Ziel der teutolabs ist es, durch spannende Experimente schon früh (im Grundschulalter) Interesse für die naturwissenschaftlichen Fächer und Mathematik zu wecken. Besonders Chemie und Physik leiden seit Jahren bundesweit unter niedrigen Studierendenzahlen. Nicht zuletzt durch die Erfolge der von Experten als in Deutschland führend angesehenen Bielefelder Labors gibt es inzwischen zahlreiche Nachahmungen an anderen Universitätsstandorten.

Chemistry in the 18th and 19th Centuries

Chemistry was first introduced as an academic discipline in medical faculties, academies, botanical gardens, and museums in the late 17th century. Over the next 100 years, it became an established part of the European intellectual world. Eighteenth-century chemists were teachers and professors, authors of learned books and experimental essays, members of academies and scholarly societies, and frequent visitors to coffee shops and salons. Yet, they differed markedly from other savants of the time. They were passionate experimenters who spent many hours in their laboratories. Furthermore, they were learned practitioners: apothecaries, metallurgical officials, consultants, inspectors of manufactures, entrepreneurs, and members of state committees and technological boards

Hochschule Niederrhein und Verband der deutschen Lackindustrie starten bundesweit einmalige Qualifizierungsoffensive

Aus Schwächen Stärken machen die Hochschule Niederrhein und der Verband der deutschen Lackindustrie mit einem in Deutschland einmaligen Modell: der kooperativen Ausbildung zum Lackingenieur in einem Bachelor-Studiengang. Er soll der Lackindustrie den dringend benötigten qualifizierten Nachwuchs sichern und für die Fachhochschule den Praxisbezug des Studiums erhalten. Wer nach vier Jahren als Lacklaborant und Lackingenieur mit Bachelor-Abschluss ins Berufsleben tritt, hat gegenüber “normaler” Ausbildung und Studium eineinhalb Jahre eingespart.

 Mumbai, Nov 3 : India must capitalise on its vast knowledge base and lower costs to emerge as a global research and development hub for the chemicals industry, Chemicals and Fertilisers Minister Ram Vilas Paswan said Wednesday.

Addressing the inaugural session of a three-day seminar on the chemicals and pharmaceuticals industry here, Paswan said the Indian chemicals industry must aim at increasing its share in the global market.

“Our goal should be to make India a global centre for research and development by making use of its intellectual capital, its competitive advantages and low costs,” Paswan told business leaders.
