FIELD: chemistry.
SUBSTANCE: invention refers to biotechnology. What is presented is nucleic acid coding protein possessing acetyl-CoA-carboxylase activity making up the deficiency of acetyl-CoA-carboxylase in yeast, wherein a nucleotide sequence is specified in nucleic acid, which contains a nucleotide sequence: (a) coding protein consisting of the amino acid sequence SEQ ID NO:2; (b) hybridised in the hard conditions with nucleic acid complementary to SEQ ID NO:1; (c) SEQ ID NO:1; and (d) hybridised in the hard conditions with nucleic acid consisting of the complementary nucleic sequence coding protein SEQ ID NO:2; wherein SEQ ID NO:1 and 2 are disclosed in the description. There are also described: acetyl-CoA-carboxylase (SEQ ID NO:2) increasing the host-specific arachidonic acid content; a recombinant vector containing the above nucleic acid; and a cell transformed by the above vector for producing the fatty acid composition rich in arachidonic acid. What is presented is a method for producing the fatty acid composition involving culturing the above cell and collecting the fatty acid composition from the transformed cell culture.
EFFECT: invention enables producing the fatty acid composition rich in arachidonic acid in the host cell.
