Halohydrin hydrogen-halide-lyase, which catalyzes the interconversion of halohydrins to epoxides, purified from a recombinant E. coli was found to catalyze the transformation of 1,2-epoxybutane into beta-hydroxyvaleronitrile in the presence of cyanide. Chloride inhibited competitively the formation of beta-hydroxyvaleronitrile. The enzyme

A new soluble cyclodextrin derivative 6-O-(2-hydroxybutyl)-beta-cyclodextrin (6-HB-beta-CD) was prepared. Its molecular binding and recognition ability were investigated with the comparison of beta-cyclodextrin (beta-CD), 2-O-(2-hydroxypropyl)-beta-cyclodextrin (2-HP-beta-CD), 6-O-(2-hydroxypropyl)-beta-cyclodextrin (6-HP-beta-CD), and 2-O-(2-hydroxybutyl)-beta-cyclodextrin (2-HB-beta-CD). The relationship between the complex stability constants and the possible
