| Outline of Final Research Achievements |
The aim of this study was to demonstrate the functional proteins of brown algae, for which genome and gene sequence information has been prior and little progress has been made in analyzing them at the protein level. By conducting this research, it was revealed that the mannuronate C-5 epimerase of Okinawa mozuku is a thermostable enzyme. Additionally, it was shown that the brown alga itself has an enzyme that degrades alginate to the level of unsaturated monosaccharides and also has its reductase. Furthermore, the protein predicted to be the mannuronate C-5 epimerase of kelp is in fact an alginate-degrading enzyme. We also identified a brown alga β-carotene hydroxylase, the existence of which was unclear from genome analysis, and showed that it has zeaxanthin-converting activity.
