(University of the Western Cape, 2012)The Rosaceae family contains major temperate crops such as the domesticated apple(Malus x domestica Borkh.), peach (Prunus persica L. Batsch) and European pear (Pyrus communis L.). However, despite its evident economic ... -
Structural analysis of induced mutagenesis A’ protein from mycobacterium tuberculosis and of a thermophillic GH9 cellulase
(University of the Western Cape, 2014)The three-dimensional structures of proteins are important in understanding their function and interaction with ligands and other proteins. In this work, the structures of two proteins, ImuA’ from mycobacterium tuberculosis ... -
Structural Analysis of Induced Mutagenesis Protein B from Mycobacterium tuberculosis Jeremy
(University of the Western Cape, 2016)Knowing the three-dimensional structure of a protein may be useful in understanding its function. In this study, induced mutagenesis protein B (ImuB) from Mycobacterium tuberculosis was analyzed using molecular biology and ... -
Structural characterisation of the interaction between RBBP6 and the multifunctional protein YB-l
(University of the Western Cape, 2010)Retinoblastoma binding protein 6 (RBBP6) is a 250 kDa RING finger-containing protein whose function is known to be mediated through interaction with other proteins. RBBP6 plays a role in the regulation of the tumour ... -
The structure of the nitrilase from Rhodococcus Rhodochrous J1: homology modeling and three-dimensional reconstruction
(University of the Western Cape, 2006)The nitrilases are an important class of industrial enzymes that are found in all phyla. These enzymes are expressed widely in prokaryotes and eukaryotes. Nitrilases convert nitriles to corresponding acids and ammonia. ... -
The structure, function and engineering of a thermostable nitrile hydratase
(University of the Western Cape, 2008)Nitrile hydratases (NHases) are enzymes that catalyse the conversion of organocyanides to amides via a non-hydrolytic hydration reaction. They are industrially relevant enzymes, currently used in the manufacture of ... -
A study of the problems and possibilities of using the marine intertidal zone for teaching principles of ecology in senior secondary schools: A survey of biology teachers in the western cape.
(University of the Western Cape, 1994)In this study I investigate the attitudes of a group biology teachers in the Western Cape, to using the marine intertidal zone for teaching principles of ecology in senior secondary schools, by exploring the problems ... -
Synthesis of silver doped titanium dioxide nanocomposites using tea extract from Aspalathus linearis and evaluation of their antibacterial effects.
(University of the Western Cape, 2018)Despite the wide success of antimicrobial agents against waterborne pathogens, waterborne disease continues to pose a threat to both mankind and animals. A major concern is that certain bacteria have developed resistance ... -
Synthesis of silver nanoparticles and investigating their antimicrobial effects
(University of the Western Cape, 2015)Water is essential for life, yet access to safe drinking water is still a major concern worldwide due to waterborne diseases. The current study proposes silver nanoparticles (AgNPs) as an antibacterial agent. Silver ... -
Systematic approach to protein crystallization: emphasis on Vaccinia virus complement control protein (VCP)
(University of the Western Cape, 2006)This work examined the systematic approach to protein crystallization, exploring some of the techniques that have been developed to enhance the success rate of crystallization. The work was centered on two proteins; namely ... -
Targeted delivery of embelin to cancer cells
(University of the Western Cape, 2013)Apoptosis or programmed cell death is vital to the development of organisms as they maintain the balance between cell death and cell growth. Failure to activate apoptosis has been implicated in carcinogenesis and often ... -
Targeted delivery of GFP loaded polymeric nanoparticles to CD4 expressing cells using a CD4 specific aptamer
(University of the Western Cape, 2020)Human Immunodeficiency Virus (HIV), which is the cause of Acquired Immunodefiency Syndrome (AIDS) is a major global public health issue affecting over 37 million people worldwide and is responsible for claiming over 32 ... -
The effect of exogenous DIM on Brassica napus and its role in response to heavy metal stress
(University of the Western Cape, 2017)Brassica napus is a plant that is used for human and animal consumption. This plant is also used for phytoremediation due to its relatively higher level of heavy metal tolerance. In South Africa, mining is one of the main ... -
The inhibition of nitric oxide biosynthesis alters anti-oxidant capacity in soybean
(University of the Western Cape, 2016)Nitric oxide is a signalling gaseous molecule endogenously synthesized from various enzymatic and non-enzymatic sources in plants. It is known to play a crucial role in the regulation of plant physiological processes ... -
The molecular validation of miRNA's as specific biomarkers for early diagnosis of ovarian cancer
(University of the Western Cape, 2017)Ovarian Cancer (OC) is the most common reproductive and the most lethal gynaecological malignant tumour. The majority of Ovarian Cancers, comprising more than 95% of cases, emanate from the surface epithelium of the ovary, ... -
