regulation

  • induced by melibiose or raffinose ([protein|58276E6FEF9388BBC7FB79BB5A3A1EF3C3DA5BD5|MelR]) [pubmed|31138628]
  • repressed by glucose ([protein|E39AFEB7B7F28969A35C4B51CC6E7819F71C79D9|CcpA]) [Pubmed|22900538]
  • there is an additional RNA "upshift" signal in front of the [gene|C3D7C64AD0E58BF326257E23136466A237138B50|melE] gene suggestive of a [gene|C3D7C64AD0E58BF326257E23136466A237138B50|melE]-[gene|05BFEA711D82395A55B505E5A38286BE2F570350|melD]-[gene|4E766839240C8F7D56D87DF9E7B99350A83B5FF7|melC]-[gene|CDE9EF9CFB799794D525F12DEC8C4190C6298575|melA] mRNA [Pubmed|22383849]. However, there is no promoter in front of [gene|C3D7C64AD0E58BF326257E23136466A237138B50|melE], suggesting that this mRNA may be the product of mRNA processing [pubmed|31138628]
