In contrast to molecular chaperones that couple protein folding to ATP hydrolysis, protein disulfide-isomerase (PDI) catalyzes protein folding coupled to formation of disulfide bonds (oxidative folding). However, we do not know how PDI distinguishes folded, partly-folded and unfolded protein substrates. As a model intermediate in an oxidative folding(More)
Traditionally regional Australia has lagged behind urban regions from the point of view of the provision of infrastructure to facilitate communicatio n and information technology. This has generally meant the transformation to the 'new economy' has been much slower as evidenced by a dearth of businesses embracing these concepts and so 'missing out' on the(More)
This paper explores the issues that influence the diffusion of innovation as it relates to the adoption of e-commerce by Small and Medium Enterprises (SMEs). It seeks to identify factors facilitating and inhibiting such adoption across contexts – regional, small city and large city. This analysis is cross cultural so the impact of differing economic and(More)
Ecommerce is considered to provide substantial benefits to business. It enables new ways of working to emerge as organisations face the future and embrace the notion of the 'new economy'. SMEs in regional areas of Australia are lagging in their adoption of e-commerce. This paper examines the reasons for the adoption and non-adoption of ecommerce by regional(More)
The Fanconi Anemia (FA) DNA repair pathway is essential for the recognition and repair of DNA interstrand crosslinks (ICL). Inefficient repair of these ICL can lead to leukemia and bone marrow failure. A critical step in the pathway is the monoubiquitination of FANCD2 by the RING E3 ligase FANCL. FANCL comprises 3 domains, a RING domain that interacts with(More)
E-commerce is considered to provide substantial benefits to business, including SMEs (Small and Medium Enterprises), largely via improved efficiencies and raised revenue, as well as the creation of opportunities for new businesses. It enables new ways of working to emerge as organisations face the future and embrace the notion of the 'new economy'. A range(More)
In eukaryotes, translation termination is performed by eRF1, which recognizes stop codons via its N-terminal domain. Many previous studies based on point mutagenesis, cross-linking experiments or eRF1 chimeras have investigated the mechanism by which the stop signal is decoded by eRF1. Conserved motifs, such as GTS and YxCxxxF, were found to be important(More)
Prions are propagated in Saccharomyces cerevisiae with remarkable efficiency, yet we know little about the structural basis of sequence variations in the prion protein that support or prohibit propagation of the prion conformation. We show that certain single-amino-acid substitutions in the prion protein Sup35 impact negatively on the maintenance of the(More)
[180--90] unit at the head of the sequence provides the adjustable element to measure T 1 of 1 H attached to 13 C. The inter-sequence relaxation delay was set to 5 s and  values were 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 and 1.0 s to provide intensities for each 1 H resonance correlated to its 13 C in the modified HSQC and example intensity data are shown(More)
