摘要：

The nucleotide sequence of a 3007-bp DNA fragment from Thermomonospora curvata CCM3352 containing the coding and regulatory region of the alpha-amylase-encoding gene (tam) was determined. Primer extension mapping was used to determine the 5' end of the transcript, and it was demonstrated that the gene is transcribed from a unique promoter which is also functional in Streptomyces lividans TK24. Transcription of tam in T. curvata was induced by maltose, even in the presence of glucose. In S. lividans, tam was expressed constitutively. The deduced amino acid sequence reveals a considerable similarity with alpha-amylases from streptomycetes.
