ynfEFGH-dmsD operon and associated TUs in Escherichia coli K-12 genome




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


Transcription unit          
Name: ynfEFGH-dmsD
Synonym(s): ynfEFGHI
Gene(s): ynfE, ynfF, ynfG, ynfH, dmsD   Genome Browser M3D Gene expression COLOMBOS
Note(s): These genes are contiguous and their products participate in the same biological process (dimethyl sulfoxide reduction); therefore, the ynfEFGH-dmsD operon was inferred Lubitz SP,2003
Evidence: [PAGTSBP] Products of adjacent genes in the same biological process
Reference(s): [1] Lubitz SP., et al., 2003
