Electrostatic potentials of E.coli genome DNA.
Distribution of electrostatic potential of the complete sequence of E. coli genome was calculated. Comparative analysis of electrostatic patterns for 359 promoter and nonpromoter nucleotide sequences was carried out. It is found that nonpromoter regions are characterized by more homogeneous distribution of electrostatic potential with no common specific elements. Electrostatic patterns of promoter DNAs can be specified due to the presence of some distinctive motifs which may be involved as promoter signal elements in RNA-polymerase-promoter recognition.
