2.3.1.179 - 2.3.1.179 AtKAS2, DNA and amino acid sequence determination and analysis, sequence comparisons, expression pattern, the promoter is active in various tissues, also in the embryo 2.3.1.179 chimeric protein js200-FabF (the first 200 amino residues from the N-terminal of Streptomyces albus FabF and the last 200 residues from the C-terminal of Streptomyces platensis FabF are combined) is expressed in Escherichia coli BL21(DE3) cells 2.3.1.179 construction of plasmids pXspFabF(M1) and pXspFabF(M2). The resulting plasmids are transformed into Escherichia coli XL1-Blue competent cells. Subsequently, pXSpFabF(M1) and pXspFabF(M2) isolated from Escherichia coli XL1-Blue cells are transformed into the expression strain Escherichia coli BL21 (DE3) 2.3.1.179 determined with the multiple isomorphous replacement method and refined at 2.4 A resolution. Hanging drop vapor diffusion method at room temperature, using 27% PEG 8000 as precipitant, buffered at pH 7.5 with 0.1 M HEPES. The crystals grow to a size of 0.5 * 0.3 * 0.2 mm3 within 3 days. The lifetime of these crystals is very limited, they will dissolve within 10 days of their appearance. Addition of 0.1% mercaptoethanol to the reservoir solution significantly increases the life time of the crystals. Space group: P3(1)21 with cell dimensions a = 76.4 A, c = 146.8 A, gamma = 120° 2.3.1.179 expressed in Arabidopsis thaliana 2.3.1.179 expressed in Escherichia coli BL21(DE3) 2.3.1.179 expressed in Escherichia coli BL21(DE3) cells 2.3.1.179 expressed in Escherichia coli cells lacking FabF 2.3.1.179 expression in Escherichia coli
