Cumulatively, these reports show a significant proteinaceous component to the biofilm formation. 2012-11-10 maitophilia fimbriae 1 (SMF-1), which is composed of fimbrin subunits and shares significant similarity with the N-terminal amino acid sequences of several fimbrial adhesins of pathogenic Escherichia coli strains and the Cup A fimbriae in Pseudomonas aeruginosa. Similar to UPEC, P. aeruginosa express numerous CUP fimbriae, of which CupA is involved in surface adherence and autoaggregation (Vallet et al. 2001; Klebensberger et al. 2009). In contrast to Pseudomonas and UPEC, the Gram-positive Enterococci are nonmotile and, up until recently, were thought to possess no adhesive pili. 2010-03-12 Here, we report that intracellular c-di-GMP levels influence cupA-encoded fimbriae expression in Pseudomonas aeruginosa.

Cup fimbriae

HD-GYP domain-containing proteins belong to the HD superfamily of metal-dependent phosphohydrolases (11). This enzyme hydrolyzes c-di-GMP in a two-step reaction, produc-ing as a final product two molecules of GMP (Fig. 1). Contrary The FA Cup Fixtures. QUICK LINKS. Full Time.

Fimbrial assembly in P. aeruginosa occurs through the proteins encoded by cup gene clusters, cupA1-5, cupB1-6, cupC1-3, and cupE1-6. 2012-07-05 · Each cluster encodes an usher, a chaperone, and two fimbrial subunits that may be involved in the production of cell surface-associated appendages similar to Cup fimbriae of P. aeruginosa. In P. aeruginosa , these fimbriae are involved in bacterial surface attachment and biofilm formation [49] , [50] .

termed cup for chaperone-usher pathways, which may be in- volved in the assembly of novel P. aeruginosa ﬁmbrial struc- tures that are radically dif ferent from the type IV pili (5, 38). In an autoaggregative P. aeruginosa small colony variant (SCV) CupA fimbriae and the intracellular c-di-GMP concentration were found to be enhanced as compared with the clonal wild-type. The SCV morphology and the expression of CupA fimbriae were dependent on a functional PA1120 and morA gene both encoding a GGDEF domain. In Pseudomonas aeruginosa, three gene clusters (cupA, cupB, and cupC) encoding c haperone- u sher p athway components have been identified in the genome sequence of the PAO1 strain. The Cup systems differ from the Pap or Fim systems, since they obviously lack numbers of genes encoding fimbrial subunits.

Three cup gene clusters (cupA-C), involved in the assembly of cell surface fimbriae, have been shown to be involved in biofilm formation by the P. aeruginosa strains PAO1 or PAK. In PA14 isolates, a fourth cluster, named cupD, was identified within a pathogenicity island, PAPI-I, and may contribute to the higher virulence of this strain. The CupE fimbriae are produced by the multimerization of CupE1 subunits, and as for other Cup fimbriae, the assembly involves a chaperone (CupE4) and an usher protein (CupE5) (Giraud et al., 2011). In addition to CupE1, minor subunits are likely to be part of the fimbrial structure, namely CupE2, CupE3 and the putative adhesin CupE6. Know as the “sugar cup” A. Fimbriae C. Slime layer B.

In Pseudomonas aeruginosa, three gene clusters (cupA, cupB, and cupC) encoding c haperone- u sher p athway components have been identified in the genome sequence of the PAO1 strain. The Cup systems differ from the Pap or Fim systems, since they obviously lack numbers of genes encoding fimbrial subunits. Cup fimbriae play an important role in cell-to-cell interactions in the early stage of biofilm formation (Wei and Ma, 2013). The composition and functions of EPSs in the P. aeruginosa biofilm were highlighted in several reviews (Flemming and Wingender, 2010; Moradali et al., 2017). The Motile–Sessile Lifestyle Switch The networks covered in depth regulate processes such as the switch between acute and chronic virulence (GacS network), the Cup fimbriae (Roc network and Rcs/Pvr network), the aminoarabinose modification of lipopolysaccharide (a network involving the PhoQP and PmrBA TCSs), twitching motility and virulence (a network formed from the Chp chemosensory pathway and the FimS/AlgR TCS), and biofilm formation (Wsp chemosensory pathway). fimbriae, suggesting that Class 5 fimbriae may actually have diverged from CUP fimbriae in the very distant past [18]. This view is substantiated in a more recent phylogenetic analysis of fimbrial usher protein sequences, which classified all Class 5 pili into a separate group or a clade that diverged from other CUP clades [19].
