Classification: C07K,C12N

Abstract:
A fused DNA sequence which comprises a first DNA sequence encoding a heat-resistant ferredoxin or a heat-resistant adenylate.kinase fused directly or indirectly to the 5â€² end of a second DNA sequence encoding a selected protein or peptide in a reading frame, so that(1) the fused DNA sequence produces a protein in which the heat-resistant ferredoxin or the heat-resistant adenylate kinse is attached to the amino terminus of the selected protein or peptide when the fused DNA is expressed in a host cell, and (2) the fused DNA is expressed in the host cell at a higher level as compared to a corresponding DNA which comprises the DNA sequence encoding a selected protein or peptide but does not comprise the DNA sequence encoding a heat-resistant ferredoxin or a heat-resistant adenylate kinase.
