Abstract: An isolated or recombinant DNA sequence coding for a mammalian, including human, glucuronyl C5-epimarase or a functional derivative thereof capable of converting D-glucuronic acid (GlcA) to L-iduronic acid (IdoA); a recombinant expression vector comprising such DNA sequence; a host cell transformed with such recombinant expression vector; a process for the manufacture of a glucuronyl C5-epimerase or functional derivative thereof capable of converting GlcA to IdoA, comprising cultivation of a cell-line transformed with such recombinant expression vector; and a glucuronyl C5-epimerase or functional derivative thereof prepared by such process.
