>16|P07642|Arabinose operon regulatory protein|Erwinia chrysanthemi|AraC
AraC is a homodimer.
>17|P03022|Arabinose operon regulatory protein|Salmonella typhimurium|AraC
AraC is an homodimer.
>35|P43506|HTH-type transcriptional repressor Bm3R1|Bacillus megaterium|TetR
In B.megaterium cell untreated with barbiturates, Bm3R1 is present at very low levels. It is possible that as suchs low concentrations Bm3R1 molecules may tend to form homodimers for binding de perfect palindromic sequence of OIII.
>72|P21308|HTH-type transcriptional regulator luxR|Vibrio harveyi|TetR
The native protein has a molecular mass of 48,000 and most likely exits as a dimer in solution.
>73|P27246|Multiple antibiotic resistance protein marA|Escherichia coli O157:H7|AraC
MarA is a monomer.
>75|Q56070|Multiple antibiotic resistance protein marA|Salmonella typhimurium|AraC
By similarity it may be a monomer.
>100|P23217|HTH-type transcriptional regulator qacR|Staphylococcus aureus subsp. aureus Mu50|TetR
The native form of QacR was a dimer.
There are two QacR dimers per DNA operator site (IR1).
>108|P09378|L-rhamnose operon transcriptional activator rhaR|Escherichia coli|AraC
RhaR is a homodimer.
>109|P40865|L-rhamnose operon transcriptional activator rhaR|Salmonella typhimurium|AraC
Homodimer (by similarity).
>110|P09377|L-rhamnose operon regulatory protein rhaS|Escherichia coli|AraC
It is predicted that RhaS binds to rhaI as a dimer.
>128|P09164|Tetracycline repressor protein class D|Escherichia coli|TetR
The crystal structure of the class TetR(D) shows that this protein forms stable homodimers.
>146|Q02458|Urease operon transcriptional activator|Proteus mirabilis|AraC
It is postulated that UreR could form multimeric complexes upon urea binding.
>393|Q51597|Cam repressor|Pseudomonas putida|TetR
CamR forms a homodimer with molecular mass of 40 kD.
>407|Q56790|HrpXv|Xanthomonas campestris pv. vesicatoria|AraC
It is tempting to speculate that HrpXv might bind the PIP box as a dimer.
>416|Q60011|Virginiae butanolide receptor|Streptomyces virginiae|TetR
The barA product exits as a homodimer at native state.
>841|Q9AIU0|Regulatory protein TtgR|Pseudomonas putida|TetR
TtgR protein exists as a homodimer at native state.
>844|Q9AJL5|VarR|Streptomyces virginiae|TetR
VarR exits as a dimer consisting of two 27-kDa subunits.
