Secretory NanoLuc Luciferase (SERK-SigP_nLuc) in RFC[25] N-Part

NanoLuc Luciferase is engineered ATP-independent luciferase from a deep-sea shrimp which luminescense 2 magnitues higher than these from Renilla reniformis or from Photinus pyralis (firefly). Also the molecular weight of NanoLuc luciferase is twice smaller compared to other luciferase (only 19 kDa). This part encodes for a NanoLuc Luciferase which is fused to a N-terminal signal peptide for secretion (SERK signal peptide from Physcomitrella patens). This construct is flanked by RFC[25] N-part prefix and suffix. Note: This means only protein fusions to the C-terminus of this part is possible, adding promoters (typically RFC[10]) into the prefix or terminators/IRES (typically RFC[10]) into the suffix of this part is nevertheless possible.
