Abstract
Novel elgin mutants that differ from the natural eglins B and C by the replacement of one, two or three amino acids in the region of the active center (amino acids 45 and 46, Leu-Asp) by other amino acids are provided. The mutants, which can be produced by recombinant genetic engineering, have valuable pharmacological properties.
