dc.description.abstractA beta-glucosidase gene from Flavobacterium meningosepticum has been cloned and expressed in Escherichia coli. The Entire nucleotide sequence was determined and analyzed. An open-reading frame of 2,178 bp encoding a polypeptide of 726 amino acids with a calculated M-r of 79,952 was derived from the sequence. The coding region is flanked by a putative promoter and transcription terminator sequences. The nucleotide sequence accession number of the complete gene sequence in Genbank is AF015915. Based on the comparison of amino acid sequences this enzyme is classified as a family B beta-glucosidase and is highly homologous with sequences from Clostridium thermocellum, Kluyvermyces fragilis, and Agrobacterium tumefaciens. The cloned enzyme was purified to near homogeneity by ammonium sulfate fractionation (35 similar to 75%) and chromatography an a cation-exchanged column at pH 6.9. This expressed beta-glucosidase has optimum activity at pH 4.2 similar to 5.0 and 50 degrees C and is stable in the pH range of 5.0 similar to 8.1 at 25 degrees C. it showed a high specificity on the glycone portion of aryl-beta-D-glycosides. All of these characteristics are highly consistent with those of the native beta-glucosidase. (C) 1998 Elsevier Science inc.en_US
