Research ArticleOpen accessPhrase in the titleThe Use of α-MF Signal Peptide Without Spacer for Producing Insulin Aspart Precursor in Pichia pastoris KM71Popi Asri Kurniatin, Fifi Fitriyah Masduki, Neni Nurainy et al.A spacer peptide (Glu-Ala repeats) connects N-terminal of a polypeptide precursor to the signal peptide of α-mating factor (α-MF) from Saccharomyces cerevisiae. During the polypeptide precursor secretion, the signal peptide will be first cleaved by signal peptidase in the endoplasmic reticulum, followed by Kex2 endopeptidase and finally the spacer peptide is removed by dipeptidyl aminopeptidase in the Golgi apparatus.

Research ArticleOpen accessPhrase in the titleStatistical Improvement of Batch Culture with Immobilized Pichia pastoris Cells for rPOXA 1B Laccase ProductionMichelle Gouzy-Olmos, Luis M. Cháves-Tequia, María F. Rojas-Fajardo et al.Immobilized Pichia pastoris X33/pGAPZαA-LaccPost-Stop in Ca2+ alginate beads was employed for Pleurotus ostreatus rPOXA 1B laccase batch production. Sequential statistical improvement was achieved through Plackett-Burman (PBED), (PBED-T11, 29.5±0.8 UL-1), which allowed to increase activity by 2.36-fold (12.5±2.6 UL-1) obtained in a preliminary study. Following, Box-Behnken Experimental Design (BBED) was implemented and obtained enzymatic activity in PBED-T11 was further increased by … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 26 Apr 2018 · 11,776 accessesView PDF Cite
