title: Secretion of interferon by Bacillus subtilis.
abstract: Bacillus subtilis was transformed with a hybrid gene in which the sequence encoding the alpha-amylase signal peptide was joined by a linker to the sequence encoding mature human interferon alpha 2(IFN-alpha 2). The hybrid preprotein was cleaved precisely following the last amino acid of the alpha-amylase signal sequence and was secreted at 0.5--1 mg per liter. IFN-alpha 2, preceded by either one or six amino acids, has the same specific antiviral activity as IFN-alpha 2 itself.
