While the concept has been long and widely used in bacterial studies since it was first proposed in 1964, very little is known about how its component operons are arranged in a bacterial genome. We present a …

WebbThe Pho regulons of bacteria - CORE Reader Webb30 nov. 2012 · The phosphate-specific transport operon, pstSCAB-phoU, of Gram-negative bacteria is an essential part of the Pho regulon. Its key roles are to encode a high-affinity inorganic phosphate transport system and to prevent activation of PhoB in phosphate-rich environments. In general, mutations in pstSCAB-phoU lead to the constitutive expression …

Webb31 jan. 2008 · The Pho regulon is a global regulatory circuit involved in bacterial phosphate management (Wanner, 1993, 1996). It has been best studied in model cells like Escherichia coli and Bacillus subtilis . In E. coli , the Pho regulon is comprised of at least 47 genes ( Wanner et al. , 1996 ; Han et al. , 1999 ; Suziedeliene et al. , 1999 ; Harris et al. , 2001 ; …
WebbOperons are common in bacteria, but they are rare in eukaryotes such as humans. In general, an operon will contain genes that function in the same process.
