Preparation and antihypertensive activity of peptides from Porphyra yezoensis
This research was to develop a antihypertensive peptide, an efficient angiotensin converting enzyme (ACE) inhibitor (ACEI), from Porphyra yezoensis. Seven commercial enzymes were screened and then enzymatic hydrolysis conditions were optimised. The results showed that alcalase was the most effective for hydrolysis and its optimum conditions for achieving the highest antihypertensive activity of...
متن کاملAnti-cancer Effects of Polysaccharide and Phycocyanin from Porphyra Yezoensis
In this paper, phycocyanin and one component (PY-D2) in polysaccharide were obtained from Porphyra yezoensis to study for their potential anti-tumor effects. MTT proliferation assays showed that, at concentration of 500 mg/L for 72 h, PY-D2 treatment significantly inhibited the growth of four tumor cell lines, HO-8910, MCF-7, K562 and SMMC-7721, with the respective inhibition rates of 21.2%, 23...
متن کاملOccurrence of coenzyme forms of vitamin B12 in a cultured purple laver (Porphyla yezoensis).
Porphyra yezoensis (Susabinori, an edible purple laver), which was cultured aseptically for 12 weeks and then lyophilized, contained 50+/-2 microg/g of vitamin B(12) per 100 g dry weight. Coenzyme forms of vitamin B(12) (about 60% of the total vitamin B(12)) were found in the cultured purple laver aseptically, which may have the ability to biosynthesize the coenzymes.
متن کاملIsolation of porphyran-degrading marine microorganisms from the surface of red alga, Porphyra yezoensis.
Marine microorganisms degrading porphyran (POR) were found on the surface of thalli of Porphyra yezoensis. Fifteen crude microorganism groups softened and liquefied the surface of agar-rich plate medium. Among these, 11 microorganism groups degraded porphyran that consisted of sulfated polysaccharide in Porphyra yezoensis. Following isolation, 7 POR-degradable microorganisms were isolated from ...
متن کاملComparative Analysis of MicroRNAs between Sporophyte and Gametophyte of Porphyra yezoensis
Porphyra yezoensis Ueda is an intertidal marine red algae that has received increasing attention as a model organism owing to its important role in biological research and the agronomic industry. The two generations of Porphyra yezoensis, the sporophyte and the gametophyte, have the same genome but show great differences in many aspects, including structural features, habitat, and gene expressi...
