General annotation
FunctionRepresses transcription from the NMTA operator-promoter. Repression is alleviated by NI(II) or co(II).
ProductMetal sensor transcriptional regulator (ArsR-SmtB family)
CommentsRv3744, (MTV025.092), len: 120 aa. Transcriptional regulator nmtR (See Cavet et al., 2002). Highly similar to many e.g. Q9ZBF4|SC9B5.26c from Streptomyces coelicolor (120 aa), FASTA scores: opt: 480, E(): 2.4e-24, (63.25% identity in 117 aa overlap); O31844|YOZA YOZA regulator from Bacillus subtilis (107 aa), FASTA scores: opt: 249, E(): 1.6e-09, (44.8% identity in 96 aa overlap); P30340|SMTB_SYNP7|SMTB from Synechococcus sp. strain PCC 7942 (Anacystis nidulans R2) (122 aa), FASTA scores: opt: 230, E(): 2.9e-08, (46.0% identity in 87 aa overlap); etc. Equivalent to AAK48216 from Mycobacterium tuberculosis strain CDC1551 (135 aa) but shorter 15 aa. Also similar to MTCY27_22; MTCY39_25; and MTCY441_12. Contains helix-turn-helix motif at aa 47-68 (Score 1815, +5.37 SD). Belongs to the ArsR-SmtB family of transcriptional regulators.
