Characterisation of AtPNP-A - a novel arabidopsis thaliana gene with role in water and salt homeostasis
(University of the Western Cape, 2009)
Plant natriuretic peptides (PNPs) are a novel class of extracellular, systemically mobile molecules that elicit a number of plant responses important in homeostasis and growth. Natriuretic peptides were first identified ...
Characterisation of eight non-codis Ministrs in four South African populations to aid the analysis of degraded DNA
(University of the Western Cape, 2009)
In many forensic cases, such as mass disasters reconstruction cases, the recovered DNA is highly degraded. In such incidences, typing of STR loci has become one of the most powerful tools for retrieving information from ...
Mining a Chinese hyperthermophilic metagenome
(University of the Western Cape, 2007)
Metagenomic sequencing of environmental samples provide direct access to
genomic information of organisms within the respective environments. This
sequence information represents a significant resource for the identification ...
Characterisation of microbial communities associated with hypolithic environments in Antarctic Dry Valley soils
(University of the Western Cape, 2008)
The Eastern Antarctic Dry Valley region is a polar desert, where conditions of extreme aridity, high temperature fluctuations and high irradiation levels make it one of the most extreme environments on earth. Despite the ...
Screening for subtate tolerant Geobacillus pallidus RAPc8 nitrile hydratase
(University of the Western Cape, 2009)
In this study G. pallidus RAPc8 NHase mutants were screened for reduced substrate inhibition compared to the wild type enzyme. Wild type and mutant enzymes were expressed and purified using hydrophobic interaction ...
Plant natriuretic peptides - elucidation of the mechanisms of action
(University of the Western Cape, 2009)
Several lines of cellular and physiological evidence have suggested the presence of a novel class of systemically mobile plant molecules that are recognized by antibodies generated against vertebrate atrial natriuretic ...
Engineering homoaromatic substrate specificity into aliphatic-specific Geobacillus pallidus RAPc8 nitrile hydratase
(University of the Western Cape, 2007)
Geobacillus pallidus RAPc8 is a thermophilic nitrile-degrading isolate, obtained from thermal sediment samples of a New Zealand hot spring. The G. pallidus RAPc8 NHase gene has been cloned and expressed in E. coli. The ...
The diversity of key anabolic genes in antarctic hypolithons
(2009)
Antarctica is known for its pristine environments. A variety of unsuitable environmental conditions were once thought to render the continent unsuitable for sustaining life. However, metagenomic data have revealed a wealth ...
Identification of bacterial pathogenic gene classes subject to diversifying selection
(University of the Western Cape, 2009)
Availability of genome sequences for numerous bacterial species comprising of different bacterial strains allows elucidation of species and strain specific adaptations that facilitate their survival in widely fluctuating ...
Microbial diversity and gene mining in Antarctic Dry Valley mineral soils
(University of the Western Cape, 2006)
Soil communities are regarded as among the most complex and diverse assemblages of microorganisms with estimated bacterial numbers in the order of 109-1 cells.g. Studies on extreme soils however, have reported lower cell ...
