algae are classified more than 7,000 species in the world and have great
diversity among seaweeds. The number of species have been increasing by the new
classification method by gene marker and genome information. Genome contains
seaweed proteins information. Red algae are rich in proteins, especially Nori
possesses about 40% protein in dry weight, having great concern for new protein
sources. Proteins have a potential not only the source of amino acid but also
bioactive peptides. We here determined the complete genome structure of
mitochondria and chloroplast from Japanese dulse, which is a new bioresource in
Southern Hokkaido and attempted to elucidate of the bioactivity.
Dulse Red alga dulse lives in cold region from
Iwate prefecture to Hokkaido prefecture in Japan. Dulse contains high amount of
protein like Nori. Red algae have galactan (agar and carrageenan) in their cell
wall, but dulse contains xylan as the cell wall.
Functional peptides Angiotensin converting enzyme I (ACE) and
dipeptidyl peptidase 4 are the enzymes, which are related to blood pressure and
blood sugar. Peptides having specific structure repress rapid increases in
blood pressure and blood sugar by the inhibition of enzyme activities.
in silico analysis in
silico analysis is performed by using computer not in vivo and in vitro. In
this study, ACE inhibitory peptide information was obtained from database and
evaluated in the chloroplast proteins in Southern Hokkaido dulse. This
information is useful for exploring novel peptides and breeding of high value
Research purpose In
this study, we determined the complete mitochondria and chloroplast genome of
Southern Hokkaido dulse and explored peptides related to health functions.
