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 ...
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. ...
Oxylipins in Cryptococcus neoformans and related yeasts
(University of the Free State, 2007-11)
English: Literature shows that Cryptococcus neoformans is an important human pathogen
responsible for many deaths worldwide. To compound this, treatment of cryptococcal
infections has over the years been difficult. This ...
The lipid composition of the yeast genus Saccharomycopsis Schiönning
(University of the Free State, 2004-11)
English: In this study, the construction of a forecasting model, using intracellular fatty acid composition as indicator, was attempted to assist in the search for yeasts capable of producing 3-hydroxy oxylipins. In order ...
Effect of cultivation conditions on the dimorphism of and heterologous protein production by Arxula adeninivorans
(University of the Free State, 2007-11)
Arxula adeninivorans strain LS3, a dimorphic yeast with potential for biotechnological applications, has in recent years has been studied for the production of heterologous proteins. The growth kinetics of this species and ...
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. ...
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 ...
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 ...
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 ...
