Synthetic vanillate-regulated promoter for graded gene expression in Sphingomonas
Regulated promoters are an important basic genetic tool allowing, for example, gene-dosage and gene depletion studies. We have previously described a cumate-inducible promoter (P(Q5)) that is functional in diverse Alphaproteobacteria. This promoter has been engineered by combining a synthetic minimal promoter, P(syn2), and operator sites and the repressor of the Pseudomonas putida F1 cym/cmt sy...
متن کاملCloning and sequencing of the Sphingomonas (Pseudomonas) paucimobilis gene essential for the O demethylation of vanillate and syringate.
Sphingomonas (Pseudomonas) paucimobilis SYK-6 is able to grow on 5,5'-dehydrodivanillic acid (DDVA), syringate, vanillate, and other dimeric model compounds of lignin as a sole carbon source. Nitrosoguanidine mutagenesis of S. paucimobilis SYK-6 was performed, and two mutants with altered DDVA degradation pathways were isolated. The mutant strain NT-1 could not degrade DDVA, but could degrade s...
متن کاملNew inducible promoter for gene expression and synthetic biology in Yarrowia lipolytica
BACKGROUND The oleaginous yeast Yarrowia lipolytica is increasingly used as alternative cell factory for the production of recombinant proteins. At present, several promoters with different strengths have been developed based either on the constitutive pTEF promoter or on oleic acid inducible promoters such as pPOX2 and pLIP2. Although these promoters are highly efficient, there is still a lack...
متن کاملA comprehensive set of plasmids for vanillate- and xylose-inducible gene expression in Caulobacter crescentus
Caulobacter crescentus is widely used as a powerful model system for the study of prokaryotic cell biology and development. Analysis of this organism is complicated by a limited selection of tools for genetic manipulation and inducible gene expression. This study reports the identification and functional characterization of a vanillate-regulated promoter (P(van)) which meets all requirements fo...
متن کاملAlginate-dependent gene expression mechanism in Sphingomonas sp. strain A1.
Sphingomonas sp. strain A1, a Gram-negative bacterium, directly incorporates alginate polysaccharide into the cytoplasm through a periplasmic alginate-binding protein-dependent ATP-binding cassette transporter. The polysaccharide is degraded to monosaccharides via the formation of oligosaccharides by endo- and exotype alginate lyases. The strain A1 proteins for alginate uptake and degradation a...
