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 [3H]palmitic acid-labeled
Brucella abortus lysates with monoclonal antibodies. These
results demonstrate that Omp10, Omp16, and Omp19 are lipoproteins.
