The Chlamydia trachomatis Mip-like protein is a lipoprotein.
The Mip-like protein of Chlamydia trachomatis is similar to the Mip protein of Legionella pneumophila and may be equally important for the initiation of intracellular infection. This article presents data which identify the chlamydial Mip-like protein as a lipoprotein. The amino acid sequence of the Mip-like protein contains a signal peptidase II recognition sequence, as is seen in procaryotic lipoproteins. Palmitic acid was incorporated into the recombinant chlamydial Mip-like protein. Globomycin, known to inhibit signal peptidase II, inhibited processing of the recombinant Mip-like protein. Labelling of chlamydial organisms with palmitic acid revealed incorporation into the native Mip-like protein.
