Description
a fusion protein consisting of E.coli endogenous SOS system repressor LexA and fungus N.crass photosensor protein VVD with LexA carrying mutation at position 40-42 and VVD carrying mutation N56K, C71V and I135M. This part serves as an ultra sensitive photoreceptor(which can sense light as weak as moonlight) and will induce a light-dependent repression of genes with their promoter containing mutated 408 form of SOS box.
Notes
LexA carrying mutation at position 40-42 and VVD carrying mutation N56K, C71V and I135M enable the sensor recognize 408 form of SOS box and with enhanced performance.
