  • The Pichia Pastoris Dihydroxyacetone Kinase Is a PTS1-Containing, but Cytosolic, Protein That Is Essential for Growth on Methanol
    . 14: 759–771 (1998) The Pichia pastoris Dihydroxyacetone Kinase is a PTS1-containing, but Cytosolic, Protein that is Essential for Growth on Methanol GEORG H. LU} ERS†, RAJ ADVANI, THIBAUT WENZEL AND SURESH SUBRAMANI* Department of Biology, University of California at San Diego, La Jolla, California 92093–0322, U.S.A. Received 11 November 1997; accepted 27 January 1998 Dihydroxyacetone kinase (DAK) is essential for methanol assimilation in methylotrophic yeasts. We have cloned the DAK gene from Pichia pastoris by functional complementation of a mutant that was unable to grow on methanol. An open reading frame of 1824 bp was identified that encodes a 65·3 kDa protein with high homology to DAK from Saccharomyces cerevisiae. Although DAK from P. pastoris contained a C-terminal tripeptide, TKL, which we showed can act as a peroxisomal targeting signal when fused to the green fluorescent protein, the enzyme was primarily cytosolic. The TKL tripeptide was not required for the biochemical function of DAK because a deletion construct lacking the DNA encoding this tripeptide was able to complement the P. pastoris dakÄ mutant. Peroxisomes, which are essential for growth of P. pastoris on methanol, were present in the dakÄ mutant and the import of peroxisomal proteins was not disturbed. The dakÄ mutant grew at normal rates on glycerol and oleate media. However, unlike the wild-type cells, the dakÄ mutant was unable to grow on methanol as the sole carbon source but was able to grow on dihydroxyacetone at a much slower rate. The metabolic pathway explaining the reduced growth rate of the dakÄ mutant on dihydroxyacetone is discussed.

Bioprocess efficiency as a roadmap to establish Pichia pastoris as a reliable cell factory ABSTRACT The present work is focused, with a bioprocess engineering point of view, in the production of the heterologous Rhizopus oryzae lipase expressed in the methylotrophic yeast Pichia pastoris under the control of the methanol-induced alcohol oxidase 1 promoter; and, specially, the improvement of the bioprocess efficiency by the use of proper operational strategies in fed-batch mode for bioreactors of different scale. With that, P. pastoris is stablished as a versatile, robust and competent platform for the production of recombinant proteins. In a first part of the dissertation, the emphasis is put on reaching optimal levels of the main performance indexes of industrial interest at lab scale in methanol feeding strategies as the only carbon source and inducer.

  • High Yield Protein Production from Pichia Pastoris Yeast
    Pichia pastoris Protocol for Growth in a Fermentor High Yield Protein Production from Pichia pastoris Yeast: A Protocol for Benchtop Fermentation By Julia Cino, PhD Introduction Over the last several decades, geneticists have learned how to manipulate DNA to identify, excise, move and place genes into a variety of organisms that are quite different genetically from the source organism. A major use for many of these recombinant organisms is to produce proteins. Since many proteins are of immense commercial value, numerous studies have focused on finding ways to produce them inexpensively, easily and in a fully functional form. The production of a functional protein is intimately related to the cellular machinery of the organism producing the protein. E. coli has been the “factory” of choice for the expression of many proteins because its genome has been fully mapped and the organism is easy to handle; grows rapidly; requires an inexpensive, easy-to-prepare medium for growth; and secretes protein into the medium which facilitates recovery of the protein. However, E. coli is a prokaryote and lacks intracellular organelles, such as the endoplasmic reticulum and the golgi apparatus that are present in eukaryotes, which are responsible for modifications of the proteins being produced. Many eukaryotic proteins can be produced in E. coli but are produced in a nonfunctional, unfinished form, since glycosylation or post-translational modifications do not 1 of 12 Pichia pastoris Protocol for Growth in a Fermentor occur. Therefore, researchers have recently turned to eukaryotic yeast and mammalian expression systems for protein production.

Coughlan1, Sara J. Hanson1, Kevin P. Byrne1 and Kenneth H. Wolfe*,1 1UCD Conway Institute, School of Medicine, University College Dublin, Dublin 4, Ireland *Corresponding author: E-mail: [email protected] Abstract Centromere organization has evolved dramatically in one clade of fungi, the Saccharomycotina. These yeasts have lost the ability to make normal eukaryotic heterochromatin with histone H3K9 methylation, which is a major component of pericentromeric regions in other eukaryotes. Following this loss, several different types of centromere emerged, including two types of sequence-defined (‘point’) centromeres, and the epigenetically-defined ‘small regional’ centromeres of Candida albicans. Here we report that centromeres of the methylotrophic yeast Komagataella phaffii (formerly called Pichia pastoris) are structurally-defined. Each of its four centromeres consists of a 2-kb inverted repeat (IR) flanking a 1-kb central core (mid) region. The four centromeres are unrelated in sequence. CenH3 (Cse4) binds strongly to the cores, with a decreasing gradient along the IRs. This mode of organization resembles Schizosaccharomyces pombe centromeres but is much more compact and lacks the extensive flanking heterochromatic otr repeats. Different isolates of K. phaffii show polymorphism for the orientation of the mid regions, due to recombination in the IRs.

    International Journal of Molecular Sciences Article Optimisation of Recombinant Myrosinase Production in Pichia pastoris Zuzana Rosenbergová 1, Kristína Kántorová 1, Martin Šimkoviˇc 2, Albert Breier 2 and Martin Rebroš 1,* 1 Institute of Biotechnology, Faculty of Chemical and Food Technology, Slovak University of Technology, Radlinského 9, 812 37 Bratislava, Slovakia; [email protected] (Z.R.); [email protected] (K.K.) 2 Institute of Biochemistry and Microbiology, Faculty of Chemical and Food Technology, Slovak University of Technology, Radlinského 9, 812 37 Bratislava, Slovakia; [email protected] (M.Š.); [email protected] (A.B.) * Correspondence: [email protected] Abstract: Myrosinase is a plant defence enzyme catalysing the hydrolysis of glucosinolates, a group of plant secondary metabolites, to a range of volatile compounds. One of the products, isothio- cyanates, proved to have neuroprotective and chemo-preventive properties, making myrosinase a pharmaceutically interesting enzyme. In this work, extracellular expression of TGG1 myrosinase from Arabidopsis thaliana in the Pichia pastoris KM71H (MutS) strain was upscaled to a 3 L laboratory fermenter for the first time. Fermentation conditions (temperature and pH) were optimised, which resulted in a threefold increase in myrosinase productivity compared to unoptimised fermentation conditions. Dry cell weight increased 1.5-fold, reaching 100.5 g/L without additional glycerol feeding. Overall, a specific productivity of 4.1 U/Lmedium/h was achieved, which was 102.5-fold higher compared to flask cultivations.
