pubmed:abstractText |
The alpha-amylase gene (amy) of Streptomyces lividans TK24 was cloned in an amylase deficient mutant strain S. lividans M2. The cloned gene contained an open reading frame (ORF) of 2757 nucleotides (919 amino acids) coding for a protein of 100 kDa. Sequencing of the amino terminus of the extracellular alpha-amylase protein revealed the presence of a signal peptide of 33 amino acid residues. The transcriptional initiation site was mapped by the primer extension method with T4 DNA polymerase and was found to be transcribed from an unique promoter. The alpha-amylase protein produced by S. lividans was larger than those derived from other origins. It also contained the four common conserved regions characteristic of other alpha-amylase proteins.
