摘要:
A crystalline structure of glutaminyl cyclase (QC). is described. Also described are the methods of preparing the crystalline structure of QC and the methods for identifying candidate inhibitors of QC. In addition, a structural basis for the rational design or identification of new inhibitors that may be used to treat QC-associated disorders is also described.

摘要:
A vector for expressing a soluble glutaminyl cyclase (QC) in bacterial cells is described. The vector contains a sequence encoding a fusion QC, which has a fusion protein tag selected from a Nus protein tag or a thioredoxin (Trx) tag, a QC, and a linker having at least one (His)x-tag between the QC and the fusion protein tag, in which x is an integer of at least 6. Methods for expressing a soluble glutaminyl cyclase (QC) by the vector are also described.
摘要:
A cis-TEVP fusion protein including a TEVP protease, a TEVP cleavage site and a target protein provide a platform for expression of the target protein. A trans-TEVP fusion protein including a TEVP cleavage site and a target protein, the amino-terminal portion of the target protein adjacent to the C-terminal portion of the TEVP cleavage site, the amino acidic residue in position P2 of the TEVP cleavage site being a Valine also produces the target protein by the same process. A cis-TEVP fusion protein system comprising the first fusion protein and a suitable host cell; a trans-TEVP fusion protein system comprising the second fusion protein and a suitable host cell; associated methods to produce target proteins, and kits of parts are also disclosed herein.
