Characterization of an α-l-rhamnosidase from Aspergillus kawachii and its gene
An α-l-rhamnosidase was purified by fractionating a culture filtrate of Aspergillus kawachii grown on l- rhamnose as the sole carbon source and retained more than 80% of its original activity following incubation at 60 °C for 1 h. Expand
Characterization of two distinct feruloyl esterases, AoFaeB and AoFaeC, from Aspergillus oryzae
Two hypothetical proteins, showing sequence identity with known type-C feruloyl esterase-encoding genes, have been found in the genomic sequence of Aspergillus oryzae and exhibited hydrolytic activity toward chlorogenic acid and methyl caffeate and methyl p-coumarate. Expand
Biochemical characterization of a glycoside hydrolase family 61 endoglucanase from Aspergillus kawachii
The glycoside hydrolase family 61 endoglucanase from Aspergillus kawachii (AkCel61) is a modular enzyme that consists of a catalytic domain and a carbohydrate-binding module belonging to family 1Expand
Isopimarane diterpene glycosides, isolated from endophytic fungus Paraconiothyrium sp. MY-42.
Six isopimarane diterpenes, compounds 1-6, were isolated from the endophytic fungus Paraconiothyrium sp. MY-42. Compound 1 possesses a 19-glucopyranosyloxy group. Its structure was first elucidatedExpand
Biochemical characterization of Aspergillus oryzae native tannase and the recombinant enzyme expressed in Pichia pastoris.
Catalytic efficiencies of both purified enzymes were greater with natural substrates than those with synthetic substrates, such as methyl, ethyl, and propyl gallates, but there were no activities against the methyl esters of ferulic, p-coumaric, caffeic, and sinapic acids, which indicate feruloyl esterase activity.

Relative abundance of Delta(5)-sterols in plasma membrane lipids of root-tip cells correlates with aluminum tolerance of rice.
Results indicate that PM lipid composition is a factor underlying variations in Al tolerance among rice cultivars. Expand
A novel Aspergillus oryzae esterase that hydrolyzes 4‐hydroxybenzoic acid esters
The purified recombinant protein showed a hydrolytic activity toward the ethyl, propyl, or butyl esters of 4‐hydroxybenzoic acid, but did not show feruloyl esterase or tannase activity. Expand
Isolation and Structure Elucidation of Neofusapyrone from a Marine-derived Fusarium species, and Structural Revision of Fusapyrone and Deoxyfusapyrone
Three polyketides containing a pyrone ring, neofusapyrone, fusapyrone, and deoxyfusapyrone, were isolated from the marine-derived fungus Fusarium sp. FH-146. Their structures were determined byExpand
A new antiplasmodial sterol from Indonesian marine sponge, Xestospongia sp
A new antimalarial sterol, kaimanol was isolated from the Indonesian Marine sponge and compared to those related compounds previously reported, which exhibited antiplasmodial activity against Plasmodium falciparum 3D7 strains. Expand
New polyketides, paralactonic acids A-E produced by Paraconiothyrium sp. SW-B-1, an endophytic fungus associated with a seaweed, Chondrus ocellatus Holmes.
Five polyketides, paralactonic acids A-E (1-5) were isolated from Paraconiothyrium sp. SW-B-1, an endophytic fungus isolated from the seaweed, Chondrus ocellatus Holmes. Their structures wereExpand
