摘要:
The invention provides Poly-(α-L-aspartic acid) (= poly-L-α-Asp), Poly-(α-L-glutamic acid) and new copolymers of L-Asp and L-Glu with essentially α-linkages as well as salts of said polymers and copolymers. A method for producing said polyamino acids comprises employing an oligonucleotide construct encoding the sequence of the desired polymer, cloning the oligonucleotide into a plasmid, transformation of host cells with the plasmid and expression of the genetic information. Because of their good biological degradability the new poly-L-α-amino acids can be used as co-builders, sequestering agents and corrosion inhibitors.
