K28, a unique double-stranded RNA killer virus of Saccharomyces cerevisiae (1990)

Schmitt, Manfred J., Tipper, Donald J.

The double-stranded RNA (dsRNA) viruses of Saccharomyces cerevisiae consist of 4.5-kilobase-pair (kb) L species and 1.7- to 2.1-kb M species, both found in cytoplasmic viruslike particles (VLPs). The...

Viral Preprotoxin Signal Sequence Allows Efficient Secretion of Green Fluorescent Protein by Candida glabrata, Pichia pastoris, Saccharomyces cerevisiae, and Schizosaccharomyces pombe

Eiden-Plach, Antje, Zagorc, Tatjana, Heintel, Tanja, Carius, Yvonne, Breinig, Frank, Schmitt, Manfred J.

Besides its importance as model organism in eukaryotic cell biology, yeast species have also developed into an attractive host for the expression, processing, and secretion of recombinant proteins....

Dual targeting of yeast catalase A to peroxisomes and mitochondria.

Petrova, Ventsislava Y, Drescher, Diane, Kujumdzieva, Anna V, Schmitt, Manfred J

Yeast catalase A (Cta1p) contains two peroxisomal targeting signals (SSNSKF) localized at its C-terminus and within the N-terminal third of the protein, which both can target foreign proteins to...

Dissecting toxin immunity in virus-infected killer yeast uncovers an intrinsic strategy of self-protection

Breinig, Frank, Sendzik, Tanja, Eisfeld, Katrin, Schmitt, Manfred J.

Toxin-secreting “killer” yeasts were initially identified >40 years ago in Saccharomyces cerevisiae strains infected with a double-stranded RNA “killer” virus. Despite extensive research...

Cell Surface Expression of Bacterial Esterase A by Saccharomyces cerevisiae and Its Enhancement by Constitutive Activation of the Cellular Unfolded Protein Response▿ †

Breinig, Frank, Diehl, Björn, Rau, Sabrina, Zimmer, Christian, Schwab, Helmut, Schmitt, Manfred J.

Yeast cell surface display is a powerful tool for expression and immobilization of biocatalytically active proteins on a unicellular eukaryote. Here bacterial carboxylesterase EstA from Burkholderia...

Exploiting the Yeast L-A Viral Capsid for the In Vivo Assembly of Chimeric VLPs as Platform in Vaccine Development and Foreign Protein Expression

Powilleit, Frank, Breinig, Tanja, Schmitt, Manfred J.

A novel expression system based on engineered variants of the yeast (Saccharomyces cerevisiae) dsRNA virus L-A was developed allowing the in vivo assembly of chimeric virus-like particles (VLPs) as a...

Retrotranslocation of a viral A/B toxin from the yeast endoplasmic reticulum is independent of ubiquitination and ERAD

Heiligenstein, Susanne, Eisfeld, Katrin, Sendzik, Tanja, Jimenéz-Becker, Natalia, Breinig, Frank, Schmitt, Manfred J

K28 is a viral A/B toxin that traverses eukaryotic cells by endocytosis and retrograde transport through the secretory pathway. Here we show that toxin retrotranslocation from the endoplasmic...

Viral killer toxins induce caspase-mediated apoptosis in yeast

Reiter, Jochen, Herker, Eva, Madeo, Frank, Schmitt, Manfred J.

In yeast, apoptotic cell death can be triggered by various factors such as H2O2, cell aging, or acetic acid. Yeast caspase (Yca1p) and cellular reactive oxygen species (ROS) are key regulators of...
