  • 产品描述：

    In the production of recombinant C.trachomatis ompA protein, the gene for ompA (E.coli) was cloned into a vector and expressed as ompA protein in E.coli. The plasmids with the copy of ompA, or the expression vector, were often used to enhance gene expression. Every step of production was undergone with a strict QC system. N-terminal 6xHis-SUMO tag was used in the process. The purity is 90% determined by SDS-PAGE.

    OmpA was first identified as a heat-modifiable protein in Escherichia coli (E. coli) in 1974 and originally purified in 1977. Its molecular mass ranges from 28 kDa to 36 kDa. OmpA family is a group of surface-exposed, porin proteins with high-copy number in Omps of GNB. N-terminal domain of OmpA is an antiparallel β-barrel structure consisting of eight transmembrane strands so as to be embedded in the outer membrane. Among those OMPs of A. baumannii, OmpA is the most deeply studied virulence factor which plays key roles in regulating the adhesion, aggressiveness, and biofilm formation of A. baumannii and immune response of host. Overproduction of OmpA is an independent risk factor for the mortality rate of nosocomial pneumonia and bacteremia caused by A. baumannii. Recent studies suggested that OmpA plays a key role in maintaining bacterial surface integrity. Generally, in GNB species, OmpA stabilize their structure by self-dimerization, which prevents the bending connections between βbarrel structure and periplasmic from being lysed.

  • 功能：
    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.
