Catalytic properties of an Escherichia coli formate dehydrogenase mutant in which sulfur replaces selenium.
Formate dehydrogenase H of Escherichia coli contains selenocysteine as an integral amino acid. We have purified a mutant form of the enzyme in which cysteine replaces selenocysteine. To elucidate the essential catalytic role of selenocysteine, kinetic and physical properties of the mutant enzyme wer...
