A 2.1-kb DNA fragment containing the SWA2 gene determining an alpha-amylase from Schwanniomyces occidentalis has been sequenced. It contains an open reading frame of 1521 bp which has the potential to encode a 507 amino-acid protein of M(r) 55966. Its deduced amino-acid sequence shows significant similarities to the sequence of other studied alpha-amylases. These similarities identify a consensus sequence, F(LIV)(ED)NHD, which is shared in addition by most maltases, invertases and glucoamylases.
已对一个包含来自西方许旺酵母中决定α-淀粉酶的SWA2基因的2.1 kb DNA片段进行了测序。它包含一个1521 bp的开放阅读框，有可能编码一个M(r)为55966的507个氨基酸的蛋白质。其推导的氨基酸序列与其他已研究的α-淀粉酶序列显示出显著相似性。这些相似性确定了一个共有序列F(LIV)(ED)NHD，大多数麦芽糖酶、转化酶和葡糖淀粉酶也共享该序列。
