Transcription unit          
Name: gcvTHP
Synonym(s): OP00232, gcv
Gene(s): gcvP, gcvH, gcvT   Genome Browser M3D Gene expression COLOMBOS
Note(s): The gcvTHP operon is expressed at a higher level in LB medium than in minimal medium. Glycine enhances its expression under minimal medium conditions Yang D,2020.
Based on gene expression analysis, it was shown that CsgD could positively regulate gcvTHP expression Herrington MB,2013
