Δ 4,5 glycuronidase nucleic acid compositions

An isolated nucleic acid molecule selected from the group consisting of

• (a) nucleic acid molecules which hybridize under stringent conditions to a nucleic acid molecule having a nucleotide sequence set forth as SEQ ID NO:2, wherein the hybridization conditions are hybridization at 65° C. in hybridization buffer comprising 3.5×(0.15M sodium chloride/0.015M sodium citrate, pH7), 0.02% Ficoll, 0.02% polyvinyl pyrrolidone, 0.02% bovine serum albumin, 25 mM NaH2PO4, pH 7, 0.5% sodium dodecylsulphate and 2 mM ethylene diamine tetra acetic acid,
• (b) nucleic acid molecules that differ from the nucleic acid molecules of (a) in codon sequence only due to degeneracy of the genetic code, and
• (c) full complements of (a) or (b).
