| Abstract: | "The pheromone 3-encoding gene (phr3) of Euplotes octocarinatus was expressed in Escherichia coli using a novel expression-secretion vector. The vector, pExSec1, contains a strong and tightly regulated T7 promoter, the corresponding Shine-Dalgarno sequence and the T7 terminator region. Translation starts at the protein A leader sequence followed by the synthetic ZZ sequence of protein A. The expression-secretion modules are embedded in the high-copy-number plasmid vector, pUK21, which carries a kanamycin-resistance marker (KmR). The produced ZZ-pheromone 3 (Phr3) fusion protein was secreted into the culture medium of the host cells. It was isolated by affinity chromatography and was further purified by gel filtration. After refolding with protein disulfide isomerase (PDI), the fusion protein exhibited the same high activity as the native pheromone" |
