The role of post translational modifications in the regulation of binding of linker histone Hho1 to chromatin in Saccharomyces cerevisiae
(University of the Free State, 2015-02)
The eukaryotic genome is functionally organized into a highly ordered nucleoprotein
structure, chromatin. Apart from the four nucleosomal core histones, the linker histone is
pivotal to fluidity and compaction of chromatin. ...

Oxylipins in the yeast genus Ascoidea
(University of the Free State, 2007-05)
English: Acetylsalicylic acid (ASA)-sensitive 3-hydroxy (3-OH) oxylipins were uncovered in 1991 in the yeast Dipodascopsis uninucleata. Since then, various similar oxylipins were found to be widely distributed in fungi. ...
Gas bubble formation in the cytoplasm yeast
(University of the Free State, 2013-11)
English:
It has previously been implicated in literature that intracellular gas bubbles cannot form in yeast cells even under high gas supersaturation conditions. Furthermore, not even protein-coated gas vesicles found ...
Identification and potential biotechnological application of yeast isolates in the UNESCO-MIRCEN biotechnological yeast culture collection of the University of the Free State
(University of the Free State, 2011-01)
English: As the initiative for establishing a yeast culture collection began in the early 1980’s in the department of Microbial, Biochemical and Food Biotechnology, research pertaining to the identification of isolates ...
Chemical modifications of core histones during exit of stationary phase in Saccharomyces cerevisae
(University of the Free State, 2011-02)
The involvement of histone acetylation in facilitating gene expression is well-established, particularly in the case of histones H3 and H4. It was previously shown in Saccharomyces cerevisiae that gene expression was ...
Yeast sensors reveal chloroquine as yeast fertility drug
(University of the Free State, 2013-11)
English: Previous unpublished research by Kock and co-workers indicated that the antimalarial drug chloroquine (CQ) stimulates yeast sexual stages (biosensors). Consequently several indicator yeasts (Eremothecium ashbyi, ...
Heterologous expression of cytochrome P450 monooxygenases in different ascomycetous yeasts
(University of the Free State, 2012-07)
Cytochrome P450 monooxygenases (P450) are a diverse, ubiquitous family of important enzymes which catalyze a variety of activities. Their outstanding abilities to hydroxylate non-activated hydrocarbons make them attractive ...
Over-expression, purification and characterization of Adh5p from Saccharomyces cerevisiae
(University of the Free State, 2010-05)
English: In the past few decades much research has been conducted on yeast alcohol
dehydrogenases with emphasis on their role in S. cerevisiae. There are seven
known Adh proteins that were identified in S. cerevisiae. ...
Enzymes from yeast adjuncts in proteolysis during cheddar cheese ripening
(University of the Free State, 2007-11)
A great deal of research in cheese technology is devoted towards the manipulation of glycolysis, lipolysis and proteolysis in order to accelerate ripening times or to improve flavour. There is increasing evidence that ...
