Molecular characterization of the pathogen-specific, 34-kilodalton membrane immunogen of Treponema pallidum.
The 34-kilodalton (kDa) antigen of Treponema pallidum subsp. pallidum (T. pallidum) is a pathogen-specific integral membrane protein. DNA sequence analysis of the cloned gene revealed an open reading frame encoding a primary product of 204 residues with a molecular mass of 22,087 daltons. Sequences that correspond to a consensus Escherichia coli promoter and a ribosome-binding site were found u...
متن کاملSequence analysis of the 47-kilodalton major integral membrane immunogen of Treponema pallidum.
The complete primary amino acid sequence for the 47-kilodalton (kDa) major integral membrane immunogen of Treponema pallidum subsp. pallidum was obtained by using a combined strategy of DNA sequencing (of the cloned gene in Escherichia coli) and N-terminal amino acid sequencing of the native (T. pallidum subsp. pallidum-derived) antigen. An open reading frame believed to encode the 47-kDa antig...
متن کاملMolecular cloning and characterization of the 15-kilodalton major immunogen of Treponema pallidum.
Pathogen-specific membrane immunogens of Treponema pallidum subsp. pallidum (T. pallidum) have been identified previously by phase partitioning with the nonionic detergent Triton X-114. One of these antigens, a 15-kilodalton (kDa) polypeptide, is expressed in relatively small quantities in T. pallidum but is highly immunogenic in both human and experimental syphilis. The native T. pallidum anti...

متن کامل
The 47-kDa major lipoprotein immunogen of Treponema pallidum is a penicillin-binding protein with carboxypeptidase activity.
The recent model of Treponema pallidum molecular architecture proposes that the vast majority of the bacterium's integral membrane proteins are lipoprotein immunogens anchored in the cytoplasmic membrane while the outer membrane contains only a limited number of surface-exposed transmembrane proteins. This unique model explains, in part, the organism's remarkable ability to evade host immune de...
