摘要:
The invention relates to methods and means for regulating gene expression and to CodY target sequences. CodY represses its target genes by binding to specific DNA sequences upstream of the respective genes. A conserved target site was identified by analyzing upstream sequences of derepressed genes in a delta codY L. lactis MG1363 derivative, as identified in a DNA micro-array study. Also, CodY target sequences from other gram-positive bacteria, like B. subtilis and Streptococcus are disclosed. Hence, the invention provides CodY target sequences that may be used in different applications to repress or derepress gene expression.

This invention provides compositions for fair-skin containing the phosphorylated polysaccharides produced by lactic acid bacteria as an effective ingredient. The phosphorylated polysaccharides are expressed, for example, by the following formula and contained in the compositions for fair-skin at concentrations of 0.01-20 weight % and are used such as creams, emulsions and toilet lotions.The compositions for fair-skin exhibit fair-skin effect by inhibiting activities to melanoma proliferation and melanin formation. ##STR1## (wherein, Glc, Gal and Rha represent glucose, galactose and rhamnose residues, respectively. Numerals shown by other than subscript represent the respective binding sites and n represents the degree of polymerization of 1,000-5,000).
