Expression of Enterocin A in Saccharomyces cerevisiaeNARA Subscribed
Recombinant expression in the yeast Saccharomyces cerevisiae offers an alternative approach to developing large-scale production systems for class II bacteriocins from lactic acid bacteria, such as enterocin A, mundticin ST4SA and plantaricin 423. An important consideration for bacteriocin activity is disulphide bond formation: mature mundticin ST4SA has one, and plantaricin 423 and enterocin A each have two disulphide bonds....
Impacts of Supplemental Feeding on Sunbird-Pollination Systems in Young Fynbos Varies with Floral AbundanceNARA Subscribed
Supplementary sugar-water feeding offers nectarivorous birds a source of spatially concentrated food, as opposed to the dispersed food available in flowers. This could impact bird visits to native flowers and alter plant-bird mutualisms, particularly in young post-fire vegetation. This study examined the effects of sugar-water feeders on nectarivorous birds and their plant mutualists in young (burned 18 months previously) and...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
Scale effects on the body size frequency distributions of A frican birds: patterns and potential mechanismsNARA Subscribed
Aim To describe and analyse the body size frequency distributions ( BSFDs ) of avian assemblages at several spatial scales in the A frotropics. We also tested if the variation in median body size across assemblages at different spatial scales was related to environmental variables and whether purely stochastic processes could explain BSFDs . Location The A frotropical biogeographic realm. Methods Avian body masses for 1960 spe...
