FIG. 1.
Molecular cloning of separate VDs of the C. pneumoniae and C. trachomatis MOMPs. The positions of the VDs are depicted schematically within the chlamydial full-length MOMP. The coding regions of the indicated MOMP fragments VD1 to VD4, along with flanking sequences, were individually cloned into a pGEX-2T expression vector, respectively (see Table 1). Amino acid (aa) positions are indicated for C. pneumoniae and C. trachomatis (in parentheses).
