LITERATURE
CeFAT-2 is expressed under the control of an inducible Gal1 promoter in Saccharomyces cerevisiae
expresed in yeast cells
-
expressed in Escherichia coli
expressed in Escherichia coli BL21(DE3) cells
-
expressed in Saccharomyces cerevisiae
expressed in Solanum tuberosum leaves as fusion protein with thermostable lichenase
-
expressed in yeast cells
-
expression in Saccahromyces cerevisae
flag-tagged enzyme is functionally expressed in yeast cells. To express the gene in thraustochytrids, a construct driven by the thraustochytrid-derived ubiquitin promoter is used
-
functional expression in Saccharomyces cerevisiae
gene desA, expression profile analysis, construction of a hybrid of desA and reporter gene encoding thermostable lichenase, licBM3, and expression in Escherichia coli strain XL1blue and Solanum tuberosum cells, the latter via Agrobacterium tumefaciens strain AGLO transfection. The desaturase can enhance tolerance to cold stress in potato, and desaturase and lichenase retain their functionality in the structure of a recombinant hybrid protein where the enzymatic activity of target gene product is higher than in the case of reporter lichenase gene absence in the construction
-
gene FAD2, DNA and amino acid sequence deterination and analysis, encoded motifs in comparison, sequence comparisons and phylogenetic analysis
recombinantly expressed in Saccharomyces cerevisiae and Pichia Pastoris
the pGEM-T Easy vector is used
