The Brucella melitensis sucB gene encoding the dihydrolipoamide succinyltransferase (E2o) enzyme (previously identified as an immunogenic protein in infected sheep) was cloned and sequenced. The amino acid sequence predicted from the cloned gene revealed 88.8 and 51.2% identity to the dihydrolipoamide succinyltransferase SucB protein from Brucella abortus and Escherichia coli, respectively. Sera from naturally infected sheep showed antibody reactivity against the recombinant SucB protein.
编码二氢硫辛酰胺琥珀酰转移酶(E2o)(先前在受感染绵羊中被鉴定为一种免疫原性蛋白)的羊种布鲁氏菌sucB基因被克隆并测序。从克隆基因预测的氨基酸序列与流产布鲁氏菌和大肠杆菌的二氢硫辛酰胺琥珀酰转移酶SucB蛋白分别有88.8%和51.2%的同一性。自然感染绵羊的血清显示出对重组SucB蛋白的抗体反应性。
