Richard Vallee is at Columbia University, College of Physicians and Surgeons in New York City. He received his BA degree from Swarthmore College, where he first majored in chemistry and then biology. In his last semester he was introduced to the new field of cell biology and the then recently identified structures called microtubules. He did his PhD at Yale in protein biophysics, and then began...

Zinc in Horse Liver Alcohol Dehydrogenase* by Bert L. Vallee

The alcohol dehydrogenase (ADH’) of yeast has twice the molecular weight of the ADH of horse liver (l), contains 4 gm. atoms of zinc (2), and binds 4 moles of DPN per mole of protein (1). The liver ADH binds 2 moles of coenzyme per mole (3). These facts prompted the prediction that the liver ADH should contain 2 gm. atoms of zinc per mole of protein (2). The presence of 2 atoms of zinc in liver...

Remembering Richard [Obituary, Richard A.Newton]

Richard Jorgensen

the well-known tendency of particular maladies to show breed-specificity can be used to infer likely sharing of descent of the causative alleles. As made clear in the volume under review, this is as true of major-gene diseases such as copper toxicosis and various retinopathies, as it is of the more complex and more prevalent cardiomyopathies, cancers, and dermatitis. Conduction of clinical tria...
