Characterization of mutants of Caulobacter crescentus defective in surface attachment of the paracrystalline surface layer.
Strains of Caulobacter crescentus express a paracrystalline surface layer (S-layer) consisting of the protein RsaA. Mutants of C. crescentus NA1000 and CB2, isolated for their ability to grow in the absence of calcium ions, uniformly no longer had the S-layer attached to the cell surface. However, RsaA was still produced, and when colonies grown on calcium-sufficient medium were examined, large...
متن کاملDevelopment of surface adhesion in Caulobacter crescentus.
Caulobacter crescentus has a dimorphic life cycle composed of a motile stage and a sessile stage. In the sessile stage, C. crescentus is often found tightly attached to a surface through its adhesive holdfast. In this study, we examined the contribution of growth and external structures to the attachment of C. crescentus to abiotic surfaces. We show that the holdfast is essential but not suffic...

shaped by their activity — both intrinsic and environment induced — and how these networks support the brain computations that underlie externally observable behavior. The second major challenge facing our young field will be applying the basic discoveries we are making to important real-world issues. It is a widely held view that understanding the brain bases of cognitive and behavioral develo...

15 صفحه اولThe S-layer of Caulobacter crescentus: three-dimensional image reconstruction and structure analysis by electron microscopy.
The regular surface protein structure (S-layer) of Caulobacter crescentus was analyzed by electron microscopy and three-dimensional image reconstruction to a resolution of 2 nm. Projections showed that the S-layer is an array of ring structures, each composed of six subunits that are arranged on a lattice with p6 symmetry. Three-dimensional reconstructions showed that the ring subunits were app...
