Work of former graduate student Tara Marcink and Steven Van Doren, professor of biochemistry, is featured as the “Molecule of the Month” in this month’s issue of PDB-101. The molecule featured is a nanodisc, which is used to conveniently package a small piece of membrane for experimental studies. This important molecule is playing a big role in a recent revolution in structural biology. PDB-101 is the educational portal of the Protein Data Bank.
