Abstract
Official abstract text for this publication.
The present invention aims to provide a promoter showing high expression activity in microorganisms belonging to the genus Mortierella . The present invention provides a polynucleotide which contains a nucleotide sequence selected from SEQ ID NOs: 1 to 28, or a variant thereof, as well as a non-human transformant containing such a polynucleotide.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vector comprising a polynucleotide selected from: (a) a polynucleotide which contains any one nucleotide sequence selected from SEQ ID NOs: 22 to 26; or (b) a polynucleotide which has a nucleotide sequence sharing an identity of 90% or more with any one nucleotide sequence selected from SEQ ID NOs: 22 to 26 and which shows promoter activity in cells of microorganisms belonging to the genus Mortierella. 2. The vector according to claim 1 , wherein the promoter activity is confirmed as β-D-glucuronidase (GUS) protein activity of at least 500 nmol/(mg·min) upon expression of GUS reporter gene in cells of microorganisms belonging to the genus Mortierella. 3. The vector according to claim 1 , which comprises any one nucleotide sequence selected from SEQ ID NOs: 22 to 26. 4. The vector according to claim 1 , which is DNA. 5. A microbial transformant transformed with the vector according to claim 1 . 6. The transformant according to claim 5 , wherein the transformant is a lipid-producing fungus. 7. The transformant according to claim 6 , wherein the lipid-producing fungus is Mortierella alpina.
