Pho operon essential
WebThe pst operon of enteropathogenic Escherichia coli enhances bacterial adherence to epithelial cells Enteropathogenic Escherichia coli (EPEC) adheres in vivo and in vitro to epithelial cells. The Phosphate (Pho) regulon is a regulatory mechanism used for the conservation and management of inorganic phosphate within the cell. It was first discovered in Escherichia coli as an operating system for the bacterial strain, and was later identified in other species. The Pho system is composed of various components including extracellular enzymes and transporters that are capable o…

WebDec 22, 2006 · The first gene in the pio operon encodes PioA, a putative decaheme c-type cytochrome. Because the ΔpioA mutant lost almost all of its Fe(II) oxidation activity, similar to the pio operon deletion mutant TIE-3, this suggests that PioA plays an essential role during Fe(II) oxidation. We postulate that it receives electrons directly from Fe(II ... WebEssential Pho Spices – The Line-Up. The spices for making pho are typically dried whole spices.
