title: [Recognition site in the restriction endonuclease Eco CK].
abstract: 5'-Terminal nucleotide was degenerated in the fragments produced by means of hydrolysis with vestrictase Eco CK. Analysis of the nucleotide sequence, carried out in four DNA fragments after the enzymatic hydrolysis' enabled to detect the only one common 13 residues nucleotide sequence, which is apparently involved in the recognizing site for vestrictase Eco CK: (A/T) (A/T) N (A/T) CGCNCNNNG. This sequence was not found in several DNA molecules with well-known primary structure, stable to the action of this enzyme.
