Abstract
A 3.1 kb fragment of Bacillus stearothermophilus ATCC12980 DNA permitted growth of Escherichia coli on sucrose. The fragment encoded genes for a levansucrase (surB) and also a levanase (surC). SurB and SurC shared 97% and 43% amino acid identity with the corresponding SacB and SacC proteins of Bacillus subtilis, whose sacB and sacC genes are organised very differently.
摘要
嗜热脂肪芽孢杆菌ATCC12980的一段3.1 kb DNA片段使大肠杆菌能够在蔗糖上生长。该片段编码一种果聚糖蔗糖酶（surB）和一种果聚糖酶（surC）的基因。SurB和SurC与枯草芽孢杆菌相应的SacB和SacC蛋白分别具有97%和43%的氨基酸同一性，而枯草芽孢杆菌的sacB和sacC基因的组织方式非常不同。
