Expression of Recombinant Protein B Subunit Pili from Vibrio Cholera
Background & Aims: Vibrio cholerae is a gram-negative bacterial pathogen that causes cholera disease. Following ingestion by a host and entry into the upper intestine, V. cholera colonizes and begins to emit enterotoxin. One of the most pathogenic factors of Vibrio cholera is toxin-coregulated pili (TCP). ToxinCoregulated pili is as the primary factor requiered for the colonization and insisten...
متن کاملStructural basis of antifreeze activity of a bacterial multi-domain antifreeze protein
Antifreeze proteins (AFPs) enhance the survival of organisms inhabiting cold environments by affecting the formation and/or structure of ice. We report the crystal structure of the first multi-domain AFP that has been characterized. The two ice binding domains are structurally similar. Each consists of an irregular β-helix with a triangular cross-section and a long α-helix that runs parallel on...
متن کاملExpression, purification, and antifreeze activity of carrot antifreeze protein and its mutants.
Antifreeze proteins (AFPs) enable organisms to survive under freezing or sub-freezing conditions. AFPs have a great potential in the low temperature storage of cells, tissues, organs, and foods. This process will require a large number of recombinant AFPs. In the present study, the recombinant carrot AFP was highly expressed in Escherichia coli strain BL21 (DE3). The activity of the purified an...
متن کاملDemonstration of antifreeze protein activity in Antarctic lake bacteria.
Antifreeze proteins (AFPs) are a structurally diverse group of proteins that have the ability to modify ice crystal structure and inhibit recrystallization of ice. AFPs are well characterized in fish and insects, but very few bacterial species have been shown to have AFP activity to date. Thirty eight freshwater to hypersaline lakes in the Vestfold Hills and Larsemann Hills of Eastern Antarctic...
متن کاملSkin-type antifreeze protein from the shorthorn sculpin, Myoxocephalus scorpius. Expression and characterization of a Mr 9, 700 recombinant protein.
A cDNA clone encoding a presumptive antifreeze protein was isolated from a skin library from shorthorn sculpin, Myoxocephalus scorpius. The clone encodes a 92-residue mature polypeptide (sssAFP-2) without any signal and prosequence, which suggests an intracellular localization. It is the largest alanine-rich, alpha-helical type I antifreeze protein known. A recombinant fusion protein containing...
