Mechanistic studies of active site mutants of Thermomonospora fusca endocellulase E2.
Biochemistry 38(30) , 9746-51, (1999) Endocellulase E2 from the thermophilic bacterium Thermomonospora fusca is a member of glycosyl-hydrolase family 6 and is active from pH 4 to 10. Enzymes in this family hydrolyze beta-1,4-glycosidic bonds with inversion of the stereochemistry at the anomeric c... |

Active-site binding of glycosides by Thermomonospora fusca endocellulase E2.
Biochemistry 37(26) , 9220-9, (1998) The determination of the high-resolution structure of the Thermomonospora fusca endocellulase E2 catalytic domain makes it ideal for exploring cellulase structure-function relationships. Here we present binding parameters (Kd, DeltaH degrees, and DeltaS degre... |

A novel polysaccharide hydrolase cDNA (celD) from Neocallimastix patriciarum encoding three multi-functional catalytic domains with high endoglucanase, cellobiohydrolase and xylanase activities.
J. Gen. Microbiol. 138(11) , 2397-403, (1992) A plant polysaccharide hydrolase cDNA, designated celD, was isolated from a cDNA library of the rumen fungus Neocallimastix patriciarum. The enzyme encoded by celD had endoglucanase, cellobiohydrolase and xylanase activities. Deletion analysis revealed that c... |

Transglycosylation activity of cellobiohydrolase I from Trichoderma longibrachiatum on synthetic and natural substrates.
Biochim. Biophys. Acta 1073(3) , 481-5, (1991) Using 4-methylumbelliferyl (MUF) beta-D-cellobioside as a substrate, the ability of cellobiohydrolase I from Trichoderma longibrachiatum to catalyze transglycosylation has been demonstrated. At substrate concentrations greater than 2 mM, the formation of MUF-... |

Cloning and expression of a Clostridium thermocellum xylanase gene in Escherichia coli.
Biochem. Mol. Biol. Int. 44(2) , 283-92, (1998) A Clostridium thermocellum xylanase gene, designated xynX, was cloned in Escherichia coli and was categorized a novel gene as a result of the comparison of restriction patterns of the C. thermocellum xylanase genes so far reported. The xynX gene encodes a xyl... |

The bifunctional enzyme chitosanase-cellulase produced by the gram-negative microorganism Myxobacter sp. AL-1 is highly similar to Bacillus subtilis endoglucanases.
Arch. Microbiol. 168(4) , 321-7, (1997) The gram-negative bacterium Myxobacter sp. AL-1 produces chitosanase-cellulase activity that is maximally excreted during the stationary phase of growth. Carboxymethylcellulase zymogram analysis revealed that the enzymatic activity was correlated with two ban... |
