delta6 - acetylenase and delta6 - desaturase from ceratodon purpureus

摘要

The present invention relates to a process for preparing unsaturated fatty acids and to a process for preparing triglycerides with an increased content of unsaturated fatty acids. The invention further relates to the use of DNA sequences coding for Delta6-acetylenase/Delta6-desaturases or Delta6-desaturases for producing a transgenic organism, preferably a transgenic plant or a transgenic microorganism with increased content of fatty acids, oils or lipids with Delta6 triple bonds and/or Delta6 double bonds. The invention additionally relates to an isolated nucleic acid sequence; to an expression cassette comprising a nucleic acid sequence, a vector and organisms comprising at least one nucleic acid sequence or expression cassette. The invention additionally relates to unsaturated fatty acids and triglycerides with an increased content of unsaturated fatty acids and the use thereof.
