α-淀粉酶作为一种十分重要的酶制剂，目前工业上都是以微生物发酵法大规模生产的。从耐高温菌株Geobacillus. POT-5基因组中，用PCR的方法扩增得到该菌的α-淀粉酶基因，此基因被克隆、测序，并在原核Escherichia coli表达系统中进行表达，并对该重组酶的酶学性质进行初步的分析。

α-amylase is a very important enzyme, the mass production ofα-amylase is based on microorganism fermentation in the industry at present. The gene ofα-amylases (amyP) is amplified from the genome of the thermostable strain Geobacillus. POT-5 by PCR. This gene is cloned, sequence analysis and expressed in procaryotic expression system in E.coli. This study also develops a preliminary analysis of enzyme properties about the recombinantα-amylase.
