cysPUWAM operon and associated TUs in Escherichia coli K-12 genome




Operon      
Name: cysPUWAM
This page displays every known transcription unit of this operon and their known regulation.


Transcription unit          
Name: cysPUWAM
Synonym(s): OP00195, cysPTWAM
Gene(s): cysM, cysA, cysW, cysU, cysP   Genome Browser M3D Gene expression COLOMBOS
Note(s): cysPUWAM expression is inhibited by oleanolic and ursolic acid, which in turn affect the expression of the cysteine regulon and the stress response Grudniak AM,2011 cysPUW as well as other genes involved in sulfur metabolism were significantly upregulated in a MG1655 lysogen carrying the Stx2a phage PA8 1208335|.
The cysP gene is upregulated at 1.25 M MgSO4 (Magnesium Sulfate), which suggests that cells control the uptake of sulfate by upregulating the expression of cysP Nepal S, Kumar P,2020
