摘要:
The invention relates to recombinant proteinase K and to a method for producing recombinant proteinase K, which is characterised by the following steps: a) transformation of a host cell containing a recombinant nucleic acid that codes for the zymogenic precursor of the proteinase K, b) cultivation of the host cell in such a way that the zymogenic precursor of proteinase K occurs in the form of inclusion bodies in said host cell, c) isolation of the inclusion bodies and re-naturing under conditions, from which the protease part of the zymogenic precursor emerges in its natural conformation, d) activation and purification of the re-natured proteinase K.
摘要:
The invention relates to a method for the synthesis of peptides, peptide mimetics and/or proteins and/or for the selective N-terminal modification of peptides, peptide mimetics and/or proteins. Said method comprises the following steps: a) an amino constituent comprising at least one amino acid is prepared, b) a carboxy constituent comprising a leaving group on the carboxyl group is prepared, said carboxy constituent being a compound comprising at least one amino acid or a compound comprising at least one marker group or reporter group, and c) the amino constituent and the carboxy constituent are reacted in a reaction medium comprising at least one ionic liquid, in the presence of a protease, a peptidase and/or a hydrolase, a peptide bond being formed between the amino constituent and the carboxy constituent, splitting off the leaving group.

摘要:
A chimeric polypeptide consisting of a first and a second polypeptide chain, being chemically linked via 1 to 3 cysteine-based disulfide bridges, characterized in that said first polypeptide chain consists of 1 to 3 cysteines and 4 to 12 basic amino acids preferably selected from the group consisting of arginine, lysine and ornithine and said second polypeptide chain consists of 1 to 3 cysteines and 4 to 12 acidic amino acids selected from the group consisting of glutamate and aspartate, and each of said polypeptide chains is linked at its C- or N-terminus to a biologically active compound, is useful as a multimeric pharmaceutical agent.
