Abstract

Multimeric angiotensin-converting-enzyme-inhibitor (ACE}) containing a trypsin cleavable linker peptide between ACEI was constructed. We made synthetic DNA coding for the ACEI peptide with asymmetric and complementary cohesive ends of linker nucleotides. A tandemly repeated DNA cassette for the expression of concatameric short peptide multimers was constructed by ligating the basic units. The resultant multimeric peptide expressed as soluble and trypsin treated peptide was shown at the same retention time with chemically synthetic ACEI by HPLC. The present results showed that the technique developed for the production of the ACEI multimers with trypsin cleavable linker peptides can be generally applicable to the production of short peptide.
