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 is implicated in the binding of transfer RNA to messenger RNA (mRNA). https...
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...
(a) Construction of Δspa2Δdec chassis in which both spa2 gene (defective for CgCLP formation) and gene fragment between CEY17_RS03380 and CEY17_RS03560 (with a function of producing the precursor for lycopene production, resulting in the color change of the cells from yellow to white)...

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 research on thetype Ⅳ pilin proteinfunction and...

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 ...
