Bacterial expression of human kynurenine 3-monooxygenase: solubility, activity, purification.

abstract：:Recombinant protein expression in insect cells varies greatly from protein to protein. A fusion tag that is not only a tool for detection and purification, but also enhances expression and/or solubility would greatly facilitate both structure/function studies and therapeutic protein production. We have shown that fusi...
