Abstrakt: Chlamydia pneumoniae is an obligate intracellular human pathogen infecting epithelial cells of the upper respiratory tract. It is a Gram-negative bacteria and has a unique biphasic developmental cycle. In this study, we use two-dimensional gel electrophoresis in combination with radioactive labeling to investigate time-dependent expression and processing of C. pneumoniae proteins. We report on (i) the identification of a hypothetical protein which is expressed late in the developmental cycle and subsequently processed; we speculate that this protein may be of importance for the developmental cycle of Chlamydia; (ii) the identification of the major outer membrane protein in three different variants, which may all be present in vivo.
