WebXylose and Arabinose. Xylose and arabinose is the major constituents of hemicellulose, large quantities of which are found in agricultural waste, such as rice straw, corncobs, and parts of hard wood. Zhang et al. have described an improved Z. mobilis strain capable of producing ethanol from xylose and arabinose ( Figure 1 ). WebIn the presence of arabinose, interactions between arabinose and the N-terminal arms hold the latter over the arabinose, thus freeing the DNA-binding domains. These domains are then free to bind to I 1 and I 2, which then leads to induction of the p BAD promoter. The binding of AraC to O 1L and O 1R, left and right, directly represses the p C.
WebSep 1, 2010 · d-fucose, a structural analog of l-arabinose (5-methyl l-arabinose), also binds to AraC (Ross et al., 2003). Additionally, Lee et al. have found that the presence of IPTG interferes with arabinose induction and that mutants of AraC can be isolated in which arabinose remains an inducer, but the interfering ability of IPTG is much reduced. …
