Information analysis of Fis binding sites.
Originally discovered in the bacteriophage Mu DNA inversion system gin, Fis (Factor for Inversion Stimulation) regulates many genetic systems. To determine the base frequency conservation required for Fis to locate its binding sites, we collected a set of 60 experimentally defined wild-type Fis DNA binding sequences. The sequence logo for Fis binding sites showed the significance and likely kin...
متن کاملCorrelation between binding rate constants and individual information of E. coli Fis binding sites
Individual protein binding sites on DNA can be measured in bits of information. This information is related to the free energy of binding by the second law of thermodynamics, but binding kinetics appear to be inaccessible from sequence information since the relative contributions of the on- and off-rates to the binding constant, and hence the free energy, are unknown. However, the on-rate could...
متن کاملA genetic analysis of Xis and FIS interactions with their binding sites in bacteriophage lambda.
The bacteriophage P22-based challenge-phage system was used to study the binding of Xis and FIS to their sites in attP of bacteriophage lambda. Challenge phages were constructed that contained the X1, X2, and F sites within the P22 Pant promoter, which is required for expression of antirepressor. If Xis and FIS bind to these sites in vivo, they repress transcription from Pant, allowing lysogeni...
متن کاملTHE CALCIUM BINDING SITES OF THE BAKERS' YEAST TRANSKETOLASE
The calcium binding sites of Bakers' Yeast Transketolase (TK) was elucidated by estimating the pKa values of the functional groups that bind to calcium. These pKa's were found to be 6.25 and 7.2 relating to the pKa's of the two immidazol moieties of histidine residues on the enzyme. The rate of the binding of calcium to the enzyme was obtained separately as a function of pH. Maximum values ...
