In the presence of Mn , MntR represses the expression of mntH , through direct binding of specific sites within the promoter regions of these genes .
Hantke , K. Dual repression by Fe - Mn - MntR of the mntH gene , encoding an NRAMP-like Mn transporter in Escherichia coli .
Mn2 can bind to MntR to facilitate its binding to the mntH promoter via 5-TTT-GCCTTAAGGAAAC-3 , resulting in repression of mntH transcription .
Mn2 can bind to MntR to facilitate its binding to the mntH promoter via a palindromic sequence , resulting in repression of mntH transcription .
a different palindromic sequence _ termed MntR-box , 5-AAACATAGCAAAGGCTATGTTT-3 , thus implementing repression of mntH transcription

18 -RRB- was substituted with i.e. stemR -LSB- mut -RSB- , this MntR-independent regulation was eliminated because mntH transcription could no longer be repressed by Mn2 .
18 -RRB- was substituted with an alternative sequence , this MntR-independent regulation was eliminated because mntH transcription could no longer be repressed by Mn2 .
