May 22, 2024 · Intracellular growth attenuator IgaA, also named YrfF in E. coli, a five-transmembrane protein with two cytosolic regions proximal to the N-terminus and one periplasmic region at the C-terminus, exerts regulatory control by activating the Rcs system, thereby facilitating the transmission of signals molecules from outer membrane to the ...
3 days ago · An example of a bacteriophage known to follow the lysogenic cycle and the lytic cycle is the phage lambda of E. coli. Sometimes prophages may provide benefits to the host bacterium while they are dormant by adding new functions to the bacterial genome, in a phenomenon called lysogenic conversion.
Unlike eukaryotic cells, prokaryotic cells lack a true nucleus and complex organelles, but they have structures such as a cell wall, capsule, cytoplasm, and flagella that support their functions and survival.
