Sulfolobus acidocaldarius DSM639 produced an acid-resistant membrane-bound amylopullulanase (Apu) during growth on starch as a sole carbon and energy source. The physiological role of Apu in starch metabolism was investigated by the growth and starch degradation pattern of apu disruption mutant as well as biochemical properties of recombinant Apu. The Δapu(More)
Since aesculin, 6,7-dihydroxycoumarin-6-O-β-glucopyranoside, suppresses inflammation, we asked whether its anti-inflammatory activity is associated with the activation of nuclear factor-E2-related factor 2 (Nrf2), a key anti-inflammatory factor. Our results, however, show that aesculin marginally activated Nrf2. Since glycosylation can enhance the function(More)
