Abstract: The present invention is related to single-chain insulin having insulin activity comprising a B- and an A-chain or a modified B- and A-chain connected by a connecting peptide of from 6-11 amino acids. The single-chain insulins will have biological insulin activity and an IGF-1 receptor affinity similar to or lower than that of human insulin and a high physical stability. The single-chain insulin may contain at least one basic amino acid residues in the connecting peptide. The single-chain insulins may also be acylated in one or more Lys residues.

Abstract: A method is provided which allows high yields of acylated insulin. The method comprises expressing a singe-chain insulin precursor, preferably in yeast, cleaving the single-chain insulin precursor with a suitable protease which will open the peptide bond between the C-terminal amino group in the B-chain and a connecting peptide connecting the B chain with the A-chain, acylating the two-chain insulin intermediate in the ?-amino group in LysB29 and subjecting the acylated two-chain insulin intermediate to a proteolytic enzyme which will cleave of the N-terminal extension on the B- and A-chains on the precursor molecule.

Abstract: The present invention relates to human insulin analogues having a fast onset of action. These analogues may have amino acid in position B26 substituted with Phe, or be Des(B30) analogues of human insulin. The invention also relates to compositions comprising such insulin analogues, and to compositions comprising a mixture of an insulin analogue having a fast onset of action and insulin having a protracted action.

Abstract: Novel insulin precursors and insulin precursor analogs comprising a connecting peptide (mini C-peptide) of preferably up to 15 amino acid residues and comprising at least one Gly are provided. The precursors can be converted into human insulin or a human insulin analog. The precursors will typically have a distance between B27 (atom CG2) and A1 (atom CA) of less than 5 ?.

Abstract: Novel insulin precursors comprising a connecting peptide (mini C-peptide) of preferably up to 6 amino acid residues and comprising at least one Pro are provided. The precursors can be converted into human insulin or desB30 human insulin.

Abstract: Novel insulin precursors and insulin analogue precursors comprising a connecting C-peptide and an N-terminal extension are easy to handle in down stream processing and are expressed in high yields. The precursors are characterized in that the connecting peptide, the N-terminal extension or both contain at least one glycosylation site.

Abstract: The present invention relates to a method for expressing heterologous proteins or polypeptides in yeast by culturing a transformed yeast strain which does not contain a functional antibiotic resistance marker gene.
