*1.B.2.1.1









MomP (Omp1) major general porin (transports many small molecules including sugars and amino acids).  A transport mechanism and antigenic properties have been studied for the closely related C. pneumoniae protein (Atanu et al. 2013). The ortholog of this protein in Clamydia abortus is likely to be part of the outer membrane complex (COMC) used as a potential vaccine candidate against ovine enzootic abortion (Longbottom et al. 2019).

*1.B.2.1.2









Major outer membrance protein MomP (OmpA, Omp1, Omp1L2) of 394 aas; 1 N-terminal TMS Rodríguez-Marañón et al., 2002). This protein is covalently linked to two other cys-rich proteins via disulfide bonds, OmcA (Omp2A; Omp3) with 88 aas and 1 N-terminal TMS, and OmcB (Omp2, Omp2B) with 547 aas and 1 N-terminal TMS. Together these proteins comprise the Chlamydial outer membrane complex (COMC) (Findlay et al. 2005). MOMP is the most suitable substitute for whole cell targets for vaccine production, and its delivery as a combined systemic and mucosal vaccine is most effective (Phillips et al. 2019). It is also a drug target (Sadhasivam et al. 2019).

Outer membrane porin, OmpA-A of 259 aas.  This protein may be C-terminally truncated since it is substantially smaller than most of the other members of this family.
