The present application provides a method for identifying a protease with modified substrate specificity or other properties. The method comprises contacting a substrate with a protease such as a serine, alpha macroglobulin or p35 family protein or modified serine and a modified p35 family member or modified alpha- macroglobulin that captures the protease by forming a Cited by: ACIB-6 Microbial itaconic acid production as test case for molecular cell design Michael Sauer Metabolic engineering is much more than constructing stoichiometric reactions within cells.

Regulation of acid and alkaline extracellular protease production by Yarrowia lipolytica by David John Glover Download PDF EPUB FB2

The alkaline extracellular protease secreted by Y. lipolytica was shown to have a major role in to 43,molecular-weight conversion, and it. Abstract. XPR2 and AXP1, coding for alkaline (AEP) and acid (AXP) extracellular proteases, have been sequenced for several XPR2, the three sequenced strains are not closely related and produce significantly different levels of AEP, yet the coding sequences are identical, and there is only a single nucleotide difference in one promoter suggesting that host Cited by: 1.

Its ability to degrade proteins and lipids can be clearly visualized by the production of extracellular lipolytic and proteolytic activities, as shown in Figures 2A and 2B, respectively.

In peptone‐ or protein‐rich media, the alkaline extracellular protease (AEP) may represent up to 1–2 g/l. Alkaline extracellular protease (AEP) from Yarrowia lipolytica is synthesized as a precursor with a aa prepro-region.

They have been compared to the native promoters of glycerolphosphate dehydrogenase and alkaline protease, and to the recombinant promoter hp4d, in terms of activity and regulation by various carbon sources. pICL1, pPOT1 and pPOX2 were found to be the strongest inducible Y. lipolytica promoters.

Results. The pro-TGase gene was cloned into integrative vectors pINA (monocopy) and pINA (multicopy), and was used to transform the Y. lipolytica Po1g or Po1h strain, respectively. Expression was driven by a recombinant hp4d promoter and secretion obtained using a XPR2 pre-sequence as a signal peptide.

This volume provides an overview of the main yeast production platforms currently used and future yeast cell factories for recombinant protein production. Chapters detail approaches of genetic and metabolic engineering, co-factor containing proteins and virus-like particles, glycoproteins, and post-translational modifications of proteins.

Background: Yarrowia lipolytica, one of the most widely studied “nonconventional” oleaginous yeast species, is unable to grow on ly, we identified and overexpressed two endogenous β-glucosidases in Y.

lipolytica, thus enabling this yeast to use cello-oligosaccharides as a carbon source for this engineered yeast platform, we have now gone further.

Histoplasma capsulatum, the etiologic agent of histoplasmosis, is a systemic dimorphic fungal pathogen.H. capsulatum exists in two morphological forms: a mycelial (or filamentous) form in soil and a yeast form in the host. During infection, mycelial fragments and associated spores are inhaled by the host.
