Schrödinger makes science fun for structural biologists

Published June 17, 2011

Schrödinger, a little like a German car, has good looks and power under the hood. The 3D exterior is powered by Maestro, the primary molecular visualization interface in the Schrödinger Suite that integrates all of the other computational tools. It even supports 3D monitors and glasses that embed the user in a 3D viewing experience.

Overkill? Not so, says Woody Sherman, VP of application science at Schrödinger. Aha moments come when scientists view structures in these 3D renderings. “The most ...

Published July 27, 2016

When Alejandro Buschiazzo took on the responsibility of building a structural biology core facility in Latin America, he was taking a risk. He was an assistant professor at the Institut Pasteur in Paris, and his career as a structural biologist had only just begun. Plus the institute he was moving to, the Institut Pasteur in Montevideo, Uruguay, was also brand new.

But to Buschiazzo, the risk was worth it. “Structural biology is quite underdeveloped in Latin America, from Mexico down,” he says. “So t...

In recent work, Brian Fox and colleagues at the Great Lakes Bioenergy Research Center at the University of Wisconsin-Madison characterized glycoside hydrolases, enzymes that digest cellulose and can be used to turn plants such as switch grass into biofuels. These enzymes occur in nature with a wide range of diversity. Genomic variations yield over thousands of unique proteins that maintain a similar core function, but with a range of sweet spots for temperature, acidity, and substrate preference.

Katya Heldwein’s first investigations of herpesviruses focused on how they get into host cells. In the process, she became interested in how these viruses get back out again. Herpesviruses replicate their genomes in the cell’s nucleus and package them in capsids. But these capsids are too large to pass through the nucleus membrane pores. “It wasn’t clear how they were getting out,” says Heldwein, associate professor of molecular biology and microbiology at Tufts.

So in 2016, she solved the structure...

In 1987, when Geoff Barton was a graduate student learning computational structural biology at the University of London, just 6000 protein sequences were known, but their numbers were rising exponentially, and it was becoming clear that they had commonalities. Sequences that yield valuable functions have staying power, so they are conserved throughout evolution. Finding these recurring patterns, however, required painstaking pencil and paper comparisons.

If the rhythm of bacterial genes being transcribed was set to music, it might sound like the asymmetric beat of Bartok, a favorite composer of structural biologist and pianist Seth Darst.
