sfGFP under arabinose promoter s1 without AraC (Arashort1)

In commercially available expression vectors arabinose promoter araBAD is usually used together with a gene for AraC transcription activator / repressor to make the system independent of chromosomal copy of AraC gene. We fused the araBAD promoter without AraC reading frame, as other sugar induced promoters to sfGFP. The shorter version of the popular promoter is still functional i.e. induced by arabinose. Arabinose induced (0,4%) in a a short time (1-8h) expression is a bit lower than driven by AraC-araBAD but after a longer time like 18h the GFP level is higher than from AraC-araBAD promoter. New shorter versions of arabinose induced promoters, all originating from E. coli genome were compared to the biobrick BBa_K1481002, provided last year by Poznan_Bioinf team.
