Gaussia princeps Luciferase fragment 1

N-terminal fragment of H. gaussia luciferase for PCA (detection of protein-protein interactions).

Disulfide bonds:

• likely, many Cys in sequence

Purification

Inouye & Sahara (2008) discuss the purification and in-vitro activity of different Luciferases, including Gaussia. They indicate that Gaussia Luciferase was previously purified from insoluable fractions -- perhaps due to the high Cys content.

Goerke et al (2008) Provide optimized in-vitro expression conditions for Gaussia Luciferase based on tuning the strain from which the cell-free lysate is produced.

Issues

Purification from E. coli failed for many constructs containing this part.
