In this article we report the production of human proinsulin C-peptide with 31 amino acid residues from a precursor overexpressed in Pichia pastoris. A C-peptide precursor expression plasmid containing nine C-peptide genes in tandem was constructed a

Monomeric B27 Lys destripeptide insulin (B27 Lys DTrI) was designed and produced from its precursor expressed in Pichia pastoris through tryptic hydrolysis instead of the less efficient tryptic transpeptidation. The monomeric B27 Lys DTrI precursor (

An aspartame analogue, L-asparaginyl L-3-phenyllactic acid methyl ester was synthesized with aspartic acid replaced by asparagine and peptide bond replaced by ester bond. The aspartic acid of aspartame could be replaced by asparagine as reported in t

Destetrapeptide insulin (DTI, human insulin with B27–30 removed) was obtained from a monomeric precursor (MIP) expressed in Saccharomyces cerevisiae through tryptic transpeptidation in the presence of synthetic tetrapeptide Gly-Phe-Phe-Tyr. The in

The methylotrophic yeast Pichia pastoris, which proved successful in producing many heterologous proteins, was used to express an insulin precursor. A transformant with a high copy number of the gene integrated into the chromosome was obtained by the

Summary: [B12Thr]human insulin and [Bl2Leu]human insulin were obtained by means of site-directed random mutagenesis. [B12Thr]human insulin retains total biological activity but [B 12Leu]human insulin has much lower biological activity. Receptor bindi

B24 and B25 phenylalanines (Phe) play important roles in insulin structure and function. Insulin analogs with B24 Phe or B25 Phe replaced by biphenylalanine (Bip) were prepared by enzymatic semisynthesis. The biological activities were determined by
