FIELD: chemistry; biotechnology.
SUBSTANCE: arthrobacter luteus B bacteria strain is obtained, which is a producer of site-specific Alu BI endonuclease. Restriction endonuclease recognises and splits both strands of the DNA 5'-AGCT-3' nucleotide sequence, without methylated bases and in such a case, when in the recognition site, one or two cytosines are methylated in the C5 position or one base is methylated in the N4 position.
EFFECT: new compounds with useful biological properties.
