[Recognition of Escherichia coli promoters from the primary structure of DNA].

The perceptron algorithm has been applied for E. coli promotors searching. To choose the appropriate promoter signs the statistical analysis was performed. By the modified perceptron method a vector, which exactly divides promoters and non-promotors in the learning sequences and gives nearly the same results as the statistical vector, has been obtained. By using this vector two potential promotors have been found at the phoE-proB chromosome region.
