Characterization, cloning and sequencing of a thermostable endo-(1, 3-1, 4) beta-glucanase-encoding gene from an alkalophilic Bacillus-brevis. Applied Microbiology and Biotechnology, vol. 38(4), pp 507-5130175-7598http://hdl.handle.net/10204/2023http://hdl.handle.net/10204/2023A Bacillus brevis gene coding for an endo-(1, 3-1, 4)-beta-glucanase was cloned in Escherichia coli and sequenced. The open reading frame contains a sequence of 759 nucleotides encoding a polypeptide of 252 amino acid residues. The amino acid sequence of the beta-glucanase gene showed only a 50% similarity to previously published data for Bacillus endo-(1, 3-1, 4)-beta-glucanases. The optimum temperature and pH for enzyme activity were 65-70-degrees-C and 8-10, respectively. When held at 75-degrees-C for 1 h, 75% residual activity was measured. The molecular mass was estimated to be about 29 kDa on sodium dodecyl sulphate (SDS)-polyacrylamide gel electrophoresis and the enzyme was found to be resistant to SDS.792277 bytesapplication/pdfenCopyright: 1993 Springer VerlagBacillus brevisEscherichia coliBeta-glucanaseApplied microbiologyArticleLouw, M., Reid, S., & Watson, T.
