Abstract

The deduced sequences of the Omp10, Omp16, and Omp19 outer membrane proteins of Brucella spp. contain a potential bacterial lipoprotein processing sequence. After extraction with Triton X-114, these three proteins partitioned into the detergent phase. Processing of the three proteins is inhibited by globomycin, a specific inhibitor of lipoprotein signal peptidase. The three proteins were radioimmunoprecipitated from [(3)H]palmitic acid-labeled Brucella abortus lysates with monoclonal antibodies. These results demonstrate that Omp10, Omp16, and Omp19 are lipoproteins.

摘要

布鲁氏菌属的外膜蛋白Omp10、Omp16和Omp19的推导序列含有潜在的细菌脂蛋白加工序列。用Triton X-114提取后,这三种蛋白质分配到去污剂相中。三种蛋白质的加工受到球蛋白霉素(一种脂蛋白信号肽酶的特异性抑制剂)的抑制。用单克隆抗体从[³H]棕榈酸标记的流产布鲁氏菌裂解物中对这三种蛋白质进行放射免疫沉淀。这些结果表明Omp10、Omp16和Omp19是脂蛋白。
