In elementary bodies (EBs, the infectious stage, which is able to survive outside the host cell) provides the structural integrity of the outer envelope through disulfide cross-links with the small cysteine-rich protein and the large cysteine-rich periplasmic protein. It has been described in publications as the Sarkosyl-insoluble COMC (Chlamydia outer membrane complex), and serves as the functional equivalent of peptidoglycan., Permits diffusion of specific solutes through the outer membrane. Source: Recombinant protein corresponding to aa23-394 from Chlamydia trachomatis Major outer membrane porin, serovar B, fused to 10X His-Tag at N-terminal and Myc-Tag at C-terminal, expressed in E.coli.
