FIELD: chemistry.
SUBSTANCE: invention relates to molecular biology, biochemistry and genetic engineering. The invention discloses a nucleic acid characterised by a nucleotide sequence which encodes a protein consisting of an amino acid sequence with deletion, replacement or addition of one or more amino acids in the amino acid sequence SEQ ID NO: 2 or SEQ ID NO: 7 and having phosphatidic acid phosphatase activity, a corresponding protein, a recombinant vector, a protein expression cell and a method of producing a fatty acid composition.
EFFECT: invention can be used to produce polyunsaturated fatty acids in the food industry.
