title: Effects of selenium compounds on formate metabolism and coincidence of selenium-75 incorporation and formic dehydrogenase activity in cell-free preparations of Escherichia coli.
abstract: The effects of selenite, selenocystine, and selenomethionine in a defined growth medium on formic dehydrogenase biosynthesis in aerobically and anaerobically grown Escherichia coli have been studied. Sucrose gradient centrifugation of a partially purified enzyme demonstrated a coincidence of (75)Se incorporation and formic dehydrogenase activity.
