Comments Canonical LuxR contains a C-terminal DNA-binding domain and an N-terminal signal binding domain. M. genitalium MG_428 contains only a DNA-binding domain. LuxR DNA-binding domain binds lux boxes with the consensus sequence A[CA]CTGTAA[AT][AT]*T[TGA]ACAG[GT]T [PUB_0505]. MG_103 and MG_447 were identified as possible LuxR-regulated genes using the consensus sequence and this procedure: Use the minimal luxR promoter given from the literature and find best hits in the M. genitalium genome Filter by those which have >10 bp identity with wildtype lux box Filter by those which have >4 bp identity with sites 3-5 and 16-18 Filter by those with an 8bp palindrome or greater Because MG_428 lacks the canonical N-terminal signal binding domain we have set the fold change activity of MG_428 on MG_103 and MG_447 to 1 (no effect). Binding site has motif A[CA]CTGTAA[AT][AT]*T[TGA]ACAG[GT]T.
