title: The aman6 gene encoding a yeast mannan backbone degrading 1,6-alpha-D-mannanase in Bacillus circulans: cloning, sequence analysis, and expression.
abstract: A gene (aman6) encoding endo-1,6-alpha-D-mannanase, a yeast mannan backbone degrading enzyme from Bacillus circulans was cloned. The putative aman6 was 1,767 base pairs long and encoded a mature 1,6-alpha-D-mannanase protein of 589 amino acids and a signal peptide of 36 amino acids. The purified mature 1,6-alpha-D-mannanase from the Escherichia coli transformant showed 61-kDa protein, and N-terminal amino acid sequence and other general properties of the recombinant enzyme were identical to those of 1,6-alpha-D-mannanase from Bacillus circulans TN-31.
