Abstract:
A DNA construct which comprises a DNA sequence encoding an enzyme having xylanase activity, as measured by release of reducing sugars from birch xylan or by release of blue color from AZCL-Birch xylan, said enzyme having a pH optimum of 4-5 and a temperature optimum of 70-80.degree. C. and which DNA sequence hybridizes to a DNA sequence depicted in SEQ ID NO. 3 under the following conditions: hybridizing in 5.times.SSC, 5.times.Denhardt's solution, 50 mM sodium phosphate, pH 6.8 and 50 ug denatured sonicated calf thymus DNA for 18 hrs at about 40.degree. C. followed by washing three times in 2.times.SSC, 0.2% SDS at 40.degree. C. for 30 minutes.
