α-D-Fucopyranose (aka α-D-fucose) is a six-carbon deoxy monosaccharide. It is equivalent to 6-deoxy-D-galactose. It acts as a non-metabolizable analog of L-arabinose and inhibits induction of the L-arabinose operon in some bacteria. Other bacteria possess a mutant araC gene where D-fucose acts as a gratuitous inducer of the L-arabinose operon. D-fucose also acts as an activator of the galS promotor in E. coli. Because of its ability to regulate gene expression, there has been some interest in exploring D-fucose as a lead compound in neurodegenerative diseases or cancer.

0.4 mM and 1 mM of D-fucose was added to E. coli cultures in a media of 1 % tryptone, 0.5% yeast extract, 0.5% NaCl, and 0.1% glucose. Inhibition of operon induction was measured as the rate of isomerase production. In the strain UP1006(ara+) the degree of inhibition by D-fucose increased with an increase in D-fucose concentration and D-fucose appears to be acting as a competitive inhibitor. In 15 out of 18 D-fucose resistant mutants L-arabinose isomerase specific activity is 1.2 to 150 fold higher than their constitutive level, clearly indicating that L-arabinose is now acting as an inducer.
