Structure of the beta- 1,3-1,4-glucanase gene ofBacillus macerans: Homologies to other beta-glucanases The nucleotide sequence of an 852 base pair (bp) DNA fragment containing the entire gene coding for thermostable beta- 1,3-1,4-glucanase of Bacillus macera... R Borriss,K Buettner,P ...
Cellobiohydrolases (CBH, exo-1,4-β-glucanases, EC 3.2.1.91) cleave the ends of cellulose chains resulting with the release of oligosaccharides, such as cellobiose units. From:Reference Module in Life Sciences,2018 Also in subject areas: ...
4 β-1,3-Glucanases From Marine Gastropods β-1,3-Glucan is a group of polysaccharide comprising a β-1,3-linked glucose main chain and β-1,4-linked and/or β-1,6-linked glucose branches (Menshova et al., 2014; Pang et al., 2005) (see Fig. 1C). The sugar chain structure of...
Analysis of gene families encoding acidic and basic beta-1,3-glucanases of tobacco. Plant Defense GenesSalicylic AcidHealthy tobacco plants accumulate β-1,3-glucanases (glucan endo-1,3-β-glucosidase; EC 3.2.1.39) in their roots and ......
The accumulation of mRNA transcripts of chitinases class VII and beta-1,3-glucanases class II decreases as embryo development progresses. In later stages, it occurs mainly in actively proliferating meristems. Abstract Besides being considered pathogenesis-related proteins, chitinases and β-1,3-glucan...
4-fold induction of beta Glu activity in the embryonic axis during the first 20 h after the start of imbibition is ethylene-independent. This initial increase was followed by a later 4-fold ethylene-dependent induction in the embryonic axis starting at 50 h, which is after the onset of ethy...
Characterization of ppEG1, a member of a multigene family which encodes endo-β-1,4-glucanase in peach Three cDNA clones (pCel10, pCel20 and pCel30), each encoding different endo-β-1,4-glucanases in peach, were obtained by RT-PCR and their expression inve... L Trainotti,S Spolaor...
Generally, exo-glucanases have a tunnel-shaped active site. On encountering an available cellulose chain end, the fibril is threaded into the active site region in the CD to form a catalytically active complex (CAC). Cleavage of the glycosidic bond then typically occurs via acid-base catalysis...
