Sequence 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 کاملTP0453, a concealed outer membrane protein of Treponema pallidum, enhances membrane permeability.
The outer membrane of Treponema pallidum, the non-cultivable agent of venereal syphilis, contains a paucity of protein(s) which has yet to be definitively identified. In contrast, the outer membranes of gram-negative bacteria contain abundant immunogenic membrane-spanning beta-barrel proteins mainly involved in nutrient transport. The absence of orthologs of gram-negative porins and outer membr...
متن کاملMolecular characterization of receptor binding proteins and immunogens of virulent Treponema pallidum
Receptor binding proteins of Treponema pallidum were identified by incubation of [35S]methionine-labeled, soluble T. pallidum preparations with formaldehyde-fixed HEp-2 cells. Three major treponemal proteins (bands 1--3) that avidly bound to the eucaryotic cell surface were detected by sodium dodecylsulfate-polyacrylamide gel electrophoresis and fluorography. Brief trypsin treatment of HEp-2 ce...
متن کاملShape of Treponema pallidum.
Treponema pallidum was found to be not helical, but a flat wave twisted into one to five different planes per cell.
متن کاملMucopolysaccharidase of Treponema pallidum.
Treponema pallidum (Nichols strain) exhibited mucopolysaccharidase activity. Acidic mucopolysaccharides were broken down more rapidly by viable treponemes than by heat-inactivated treponemes or membrane filtrates of treponemal suspensions. Ouchterlony immunodiffusion demonstrated the occurrence of antibodies to the hyaluronidase-like enzyme within syphilitic sera. After intratesticular inoculat...
