>cd03324 rTSbeta_L-fuconate_dehydratase Human rTS beta is encoded by the rTS gene which, through alternative RNA splicing, also encodes rTS alpha whose mRNA is complementary to thymidylate synthase mRNA. rTS beta expression is associated with the production of small molecules that appear to mediate the down-regulation of thymidylate synthase protein by a novel intercellular signaling mechanism. A member of this family, from Xanthomonas, has been characterized to be a L-fuconate dehydratase. rTS beta belongs to the enolase superfamily of enzymes, characterized by the presence of an enolate anion intermediate which is generated by abstraction of the alpha-proton of the carboxylate substrate by an active site residue and is stabilized by coordination to the essential Mg2+ ion.
