Pili are short, hair-like structures on the cell surface ofprokaryotic cells prokaryotic cells The prokaryotic small ribosomal subunit, or 30S subunit, isthe smaller subunit of the 70S ribosomefound in prokaryotes. It is a complex of the 16S ribosomal RNA (rRNA) and 19 proteins. This complex ...
and the motility machinery in the cell is designed to respond in a positive or negative way to these gradients by directing the movement of the cell either toward or away from the signal molecule, respectively. Such directed movements are called TAXES....
In this review, we describe the adhesive properties of bacteria (to eukaryotic and prokaryotic cells, and inert surfaces) and emphasize the characteristics of adhesins (structure, function, genetics, and morphology) and their cognate ... G Jones,R. Isaacson - 《Crc Critical Reviews in Microbiolog...
In this study, we demonstrate that pilus-mediated interactions can be harnessed by T6SS-equipped V. cholerae to kill non-kin cells under liquid growth conditions. We also show that the naturally occurring diversity of pili determines the likelihood of cell-to-cell contact and, consequently, the...

Objective:To expressneuropilin-1(Nrp1)in prokaryotic system fragmentally and to identify the expression of Nrp1 in tissue and in cells with rabbit-anti-mouse Nrp1 antibodies which were gained from New Zealand rabbits immunized with the purified Nrp1 fragments. ...
Type IV pili not only serve as multifunctional organelles allowing the adherence to host cells and the auto-aggregation of these bacteria2, but also play an essential role in their pathogeneses4,5. In this paper, Neisseria meningitidis is used as a model system. Given their crucial functions ...
2) type Ⅳ pilin protein Ⅳ型菌毛蛋白 1. Objective To construct the recombinant plasmid pET32a(+)-pilE and to detect its expression in the prokaryotic cells BL21(DE3)and to purifytype Ⅳ pilin proteinof the Legionella pneumophila encoded by pilE gene so as to set the basis for future re...
Microcolonies are aggregates of a few dozen to a few thousand cells exhibited by many bacteria. The formation of microcolonies is a crucial step towards the formation of more mature bacterial communities known as biofilms, but also marks a significant change in bacterial physiology. Within a micr...
cells (TT_C1836::kat) were only defective in their ability to assemble narrow pili. To ensure that the absence of pili was not due to polar effects on nearby genes, we performed RT-PCR on downstream genes (Supplementary Fig.4a, b). The amount of transcript present was the same in ...
