Ancient origin of glycosyl hydrolase family 9 cellulase genes.
While it is widely accepted that most animals (Metazoa) do not have endogenous cellulases, relying instead on intestinal symbionts for cellulose digestion, the glycosyl hydrolase family 9 (GHF9) cellulases found in the genomes of termites, abalone, and sea squirts could be an exception. Using information from expressed sequence tags, we show that GHF9 genes (subgroup E2) are widespread in Metaz...
متن کاملDefining Cellulase in the Glycosyl Hydrolase Family 48 Sequence, Structure, and Evolution of Cellulases in the Glycoside Hydrolase Family 48
Background: Cellulases are non-homologous isofunctional enzymes, which prevents their unambiguous identification in genomic datasets. Results: Cellulases from glycoside hydrolase family 48 have distinct evolutionarily conserved sequence and structural features. Conclusion: Conserved sequence/structure features can be used to differentiate cellulases from non-cellulases in genomic datasets. Sign...

متن کاملEvolution of Cariogenic Character in Streptococcus mutans: Horizontal Transmission of Glycosyl Hydrolase Family 70 Genes
Acquisition of the ability to produce polysaccharides from sucrose, i.e. the gtf gene encoding glucosyltransferase (GTF), is the key evolutionary event enabling dental biofilm formation by streptococci. To clarify the ancestry of streptococcal GTFs, time of its occurrence, and order of specific events, we investigated the distribution of GTFs among bacteria by phylogenetic analysis of the glyco...
متن کاملA novel cellulosomal scaffoldin from Acetivibrio cellulolyticus that contains a family 9 glycosyl hydrolase.
A novel cellulosomal scaffoldin gene, termed cipV, was identified and sequenced from the mesophilic cellulolytic anaerobe Acetivibrio cellulolyticus. Initial identification of the protein was based on a combination of properties, including its high molecular weight, cellulose-binding activity, glycoprotein nature, and immuno-cross-reactivity with the cellulosomal scaffoldin of Clostridium therm...
