Cloning and sequence analysis of the major outer membrane protein gene of Chlamydia psittaci 6BC.
The gene encoding the major outer membrane protein (MOMP) of the psittacine Chlamydia psittaci strain 6BC was cloned and sequenced. N-terminal protein sequencing of the mature MOMP indicated that it is posttranslationally processed at a site identical to the site previously identified in the MOMP of Chlamydia trachomatis L2. The nucleotide sequence of the C. psittaci 6BC MOMP gene was found to ...
متن کاملCharacterization of lipoprotein EnvA in Chlamydia psittaci 6BC.
The primary sequence of the small cysteine-rich protein (EnvA) of Chlamydia psittaci 6BC has been shown to possess a potential lipid modification/signal peptidase II-processing site, and the mature protein was labeled by a [3H]palmitic acid precursor. We further characterized the mature EnvA, showing that it lacks the N-terminal methionine of the primary peptide, is hydrophobic despite a peptid...
متن کاملDissociation of immune determinants of outer membrane proteins of Chlamydia psittaci strain guinea pig inclusion conjunctivitis.
Chlamydia trachomatis is an important human pathogen. Research to develop a Chlamydia vaccine has focused on the major outer membrane protein (MOMP). Determinants of this protein elicit serovar-specific neutralizing antibodies which are thought to play a critical role in protective immunity. MOMP-specific antibody responses are highly variable in the polymorphic population. Genetic factors whic...
متن کاملSequence analysis and lipid modification of the cysteine-rich envelope proteins of Chlamydia psittaci 6BC.
The envelopes of elementary bodies of Chlamydia spp. consist largely of disulfide-cross-linked major outer membrane protein (MOMP) and two cysteine-rich proteins (CRPs). The MOMP gene of Chlamydia psittaci 6BC has been sequenced previously, and the genes encoding the small and large CRPs from this strain were cloned and sequenced in this study. The CRP genes were found to be tandemly arranged o...
متن کاملIdentification of genus-specific epitopes on the outer membrane complexes of Chlamydia trachomatis and Chlamydia psittaci immunotypes 1 and 2.
Polyclonal and monoclonal antibodies were used to study the immunogenic and antigenic characteristics of chlamydiae. We focused on the most predominant proteins in the outer membrane complex, the major outer membrane protein (MOMP) and the doublet consisting of proteins of 57 and 62 kilodaltons (57-62 kDa doublet). Immunoblot analyses were performed with chlamydial elementary bodies by using (i...
