Intermolecular recombination

Oat (Avena sativa L.) is a recognized health-food, and the contributions of its different candidate Agenome progenitor species remain inconclusive. Here, we report chloroplast genome sequences of eleven Avena species, to examine the plastome evolutionary dynamics and analyze phylogenetic relationships between oat and its congeneric wild related species.

Superantigens (SAgs) are a class of disease-causing and immunostimulatory proteins of bacterial or viral origin that activate a large number of T-cells through interaction with the Vbdomain of T-cell receptors (TCRs). In this study, recombinant TCRbchains were constructed with human variable domains Vb5.2, Vb1and Vb2.1, expressed as inclusion bodies, refolded and purified. The Streptococcus pyogenesSAg SSA-1 was cloned and expressed as a soluble periplasmicprotein. SSA-1wasobtainedbothas amonomer and a dimer that has an intermolecular disulfide bond. ...
