PROTEIN HAVING ACTIVITY TO PROMOTE FATTY ACID CHAIN ELONGATION, GENE ENCODING SAME AND USE THEREOF

摘要

The present invention relates to a protein having an activity to promote fatty acid chain elongation, a polynucleotide encoding the same, etc. The present invention provides, for example, a polynucleotide containing the nucleotide sequence shown in SEQ ID NO: 1 or 4, a polynucleotide encoding a protein which consists of the amino acid sequence shown in SEQ ID NO: 2, an expression vector and a transformant, each containing such a polynucleotide, a method for preparing lipids or fatty acids by using such a transformant, or a food or the like containing lipids or fatty acids prepared by such a method.

主权项

1. A polynucleotide of any one selected from the group consisting of (a) to (e) shown below:
(a) a polynucleotide containing the nucleotide sequence shown in SEQ ID NO: 1 or 4; (b) a polynucleotide encoding a protein which consists of the amino acid sequence shown in SEQ ID NO: 2; (c) a polynucleotide encoding a protein which consists of an amino acid sequence with deletion, substitution, insertion and/or addition of 1 to 100 amino acids in the amino acid sequence shown in SEQ ID NO: 2 and which has an activity to promote fatty acid chain elongation; (d) a polynucleotide encoding a protein which has an amino acid sequence sharing an identity of 60% or more with the amino acid sequence shown in SEQ ID NO: 2 and which has an activity to promote fatty acid chain elongation; and (e) a polynucleotide which is hybridizable under stringent conditions with a polynucleotide consisting of a nucleotide sequence complementary to the nucleotide sequence shown in SEQ ID NO: 1 or 4 and which encodes a protein having an activity to promote fatty acid chain elongation.
