Natively unfolded human prothymosin alpha adopts partially folded collapsed conformation at acidic pH.
Prothymosin alpha has previously been shown to be unfolded at neutral pH, thus belonging to a growing family of "natively unfolded" proteins. The structural properties and conformational stability of recombinant human prothymosin alpha were characterized at neutral and acidic pH by gel filtration, SAXS, circular dichroism, ANS fluorescence, (1)H NMR, and resistance to urea-induced unfolding. In...

متن کاملImproved stability of a protein vaccine through elimination of a partially unfolded state.
Ricin is a potent toxin presenting a threat as a biological weapon. The holotoxin consists of two disulfide-linked polypeptides: an enzymatically active A chain (RTA) and a galactose/N-acetylgalactosamine-binding B chain. Efforts to develop an inactivated version of the A chain as a vaccine have been hampered by limitations of stability and solubility. Previously, recombinant truncated versions...
متن کاملCurrent state of professional and core competency in pediatric residency program at Shiraz University of Medical Sciences: A local survey
Introduction: Accreditation assesses performance, or capacity toperform, against predetermined standards. It typically combinesexternal quality assurance, through a process of peers review,with elements of self-regulation through internal and selfdirectedassessment. This study is an attempt to identify thequality of pediatrics residency educational programs regardingpredetermined standards.Meth...
متن کاملRibosome-mediated folding of partially unfolded ricin A-chain.
After endocytic uptake by mammalian cells, the cytotoxic protein ricin is transported to the endoplasmic reticulum, whereupon the A-chain must cross the lumenal membrane to reach its ribosomal substrates. It is assumed that membrane traversal is preceded by unfolding of ricin A-chain, followed by refolding in the cytosol to generate the native, biologically active toxin. Here we describe bioche...
