Neisseria gonorrhoeae PilA is an FtsY homolog.
The pilA gene of Neisseria gonorrhoeae was initially identified in a screen for transcriptional regulators of pilE, the expression locus for pilin, the major structural component of gonococcal pili. The predicted protein sequence for PilA has significant homology to two GTPases of the mammalian signal recognition particle (SRP), SRP54 and SRalpha. Homologs of SRP54 and SRalpha were subsequently...
متن کاملDistribution of Pila polita in a southern province of Thailand.
This field study investigated the distribution of the freshwater snails of the family Ampullariidae in 18 provinces of Thailand. The introduced Pomacea canaliculata has wide distribution in the studied provinces. Pila angelica, P. ampullacea and P. pesmei still have limited distribution. Pila polita, which is absent in the south, now can be found in Phangnga, a southern province of Thailand. Mo...
متن کاملRegulation of expression of the pilA gene in Myxococcus xanthus.
Type IV pili are required for social gliding motility in Myxococcus xanthus. In this work, the expression of pilin (the pilA gene product) during vegetative growth and fruiting-body development was examined. A polyclonal antibody against the pilA gene product (prepilin) was prepared, along with a pilA-lacZ fusion, and was used to assay expression of pilA in M. xanthus in different mutant backgr...
متن کاملDifferential PilA pilus assembly by a hospital-acquired and a community-derived Enterococcus faecium isolate.
Pili are hair-like structures protruding from the cell envelope of bacterial cells. Here, we describe the conditional and differential display of PilA-type pili, and PilE and PilF proteins, encoded from pilin gene cluster 1 at the surface of a hospital-acquired Enterococcus faecium bloodstream isolate (E1165) and a community-derived stool isolate (E1039), at two different temperatures. Both str...
متن کاملInduction of Specific Humoral Immune Response in Mice against a Pseudomonas aeruginosa Chimeric PilQ/PilA Protein
Background: Pseudomonas aeruginosa, an opportunistic pathogen, is a common cause of healthcare-associated infections in immunocompromised individuals. The rapid emergence of multidrug-resistant strains has made P. aeruginosa infections progressively difficult to treat. In this study we evaluated the effect of a chimeric protein containing a P. aeruginosa PilQ fragment and the PilA disulfide loo...
