Abstract: Aspart modified proinsulin sequences that have a modified C-peptide amino acid and/or nucleic acid modification for producing aspart insulin analogs are provided. Highly efficient processes for preparing the aspart insulin analogs and improved preparations containing the aspart insulin analogs prepared according to the methods described herein are also provided.

Abstract: Disclosed herein are novel and improved preparations and methods for manufacturing substantially liquid preparations of recombinant human insulin API. The purified recombinant human insulin Active Pharmaceutical Ingredient (API) preparations are substantially free of by-products associated with the lyophilization and/or crystallization. The methods for manufacturing the substantially liquid recombinant human insulin API preparations are provided with optional steps for subjecting the recombinant insulin preparation to lyophilization and/or crystallization. Enhanced yield of recombinant insulin of greater purity are thereby provided according to the present invention. Highly purified formulations of recombinant human insulin of the API insulin preparations disclosed herein are also provided. Stably transformed E.

Abstract: Novel pro-insulin having specific amino acid and/or nucleic acid modifications suitable for improved methods of insulin production are provided. Novel and highly efficient processes for preparing the pro-insulin preparations and preparations containing them are also disclosed. The novel pro-insulin preparations may be converted into human insulin useful in therapeutic preparations. Novel peptides of the C-peptide, and N terminus, including RREAEALQVGQVELGGGPGAGSLQPLALEGSLQAR, and MHHHHHHGGR respectively are provided, as well as the unique nucleic acid molecules encoding them.
