Comparative genomic analysis of thermophilic fungi reveals convergent evolutionary adaptations and gene losses

Author(s): Steindorff AS; Aguilar-Pontes MV; Robinson AJ; Andreopoulos B; LaButti K; Kuo A; Mondo S; Riley R; Otillar R; Haridas S; Lipzen A; Grimwood J; Schmutz J; Clum A; Reid ID; Moisan MC; Butler G; Nguyen TTM; Dewar K; Conant G; Drula E; Henri ...

Thermophily is a trait scattered across the fungal tree of life, with its highest prevalence within three fungal families (Chaetomiaceae, Thermoascaceae, and Trichocomaceae), as well as some members of the phylum Mucoromycota. We examined 37 thermophilic and thermotolerant species and 42 mesophil ...

Substrate specificity mapping of fungal CAZy AA3_2 oxidoreductases

Author(s): Zhao H; Karppi J; Mototsune O; Poshina D; Svartström J; Nguyen TTM; Vo TM; Tsang A; Master E; Tenkanen M;

Background: Oxidative enzymes targeting lignocellulosic substrates are presently classified into various auxiliary activity (AA) families within the carbohydrate-active enzyme (CAZy) database. Among these, the fungal AA3 glucose-methanol-choline (GMC) oxidoreductases with varying auxiliary activi ...

Comparative analysis of functional diversity of rumen microbiome in bison and beef heifers

Author(s): Nguyen TTM; Badhan AK; Reid ID; Ribeiro G; Gruninger R; Tsang A; Guan LL; McAllister T;

Ruminants play a key role in the conversion of cellulolytic plant material into high-quality meat and milk protein for humans. The rumen microbiome is the driver of this conversion, yet there is little information on how gene expression within the microbiome impacts the efficiency of this conversion process. The current study investigates gene expression ...

Functional characterization of fungal lytic polysaccharide monooxygenases for cellulose surface oxidation

Author(s): Mathieu Y; Raji O; Bellemare A; Di Falco M; Nguyen TTM; Viborg AH; Tsang A; Master E; Brumer H;

Background: Microbial lytic polysaccharide monooxygenases (LPMOs) cleave diverse biomass polysaccharides, including cellulose and hemicelluloses, by initial oxidation at C1 or C4 of glycan chains. Within the Carbohydrate-Active Enzymes (CAZy) classification, Auxiliary Activity Family 9 (AA9) comp ...

Characterization of a novel AA3_1 xylooligosaccharide dehydrogenase from Thermothelomyces myriococcoides CBS 398.93

Author(s): Zhao H; Karppi J; Nguyen TTM; Bellemare A; Tsang A; Master E; Tenkanen M;

Background: The Carbohydrate-Active enZymes (CAZy) auxiliary activity family 3 (AA3) comprises flavin adenine dinucleotide-dependent (FAD) oxidoreductases from the glucose-methanol-choline (GMC) family, which play auxiliary roles in lignocellulose conversion. The AA3 subfamily 1 predominantly consists of cellobiose dehydrogenases (CDHs) that typically com ...

Identification of a Novel Biosynthetic Gene Cluster in Aspergillus niger Using Comparative Genomics

Author(s): Evdokias G; Semper C; Mora-Ochomogo M; Di Falco M; Nguyen TTM; Savchenko A; Tsang A; Benoit-Gelber I;

Previously, DNA microarrays analysis showed that, in co-culture with Bacillus subtilis, a biosynthetic gene cluster anchored with a nonribosomal peptides synthetase of Aspergillus niger is downregulated. Based on phylogenetic and synteny analyses, we show here that this gene cluster, NRRL3_00036- ...

Genomic and exoproteomic diversity in plant biomass degradation approaches among Aspergilli

Author(s): Mäkelä MR; DiFalco M; McDonnell E; Nguyen TTM; Wiebenga A; Hildén K; Peng M; Grigoriev IV; Tsang A; de Vries RP;

We classified the genes encoding carbohydrate-active enzymes (CAZymes) in 17 sequenced genomes representing 16 evolutionarily diverse Aspergillus species. We performed a phylogenetic analysis of the encoding enzymes, along with experimentally characterized CAZymes, to assign molecular function to ...
