  • Biology, Medicine
  • Annual review of microbiology
  • 1986
TLDR
The aim of this monograph is to provide a discussion of the phytochemical properties of hydrogen, as well as some of the properties of chlorine, which have been studied in greater detail in the context of an open-air setting. Expand
Thermoanaerobacter ethanolicus gen. nov., spec. nov., a new, extreme thermophilic, anaerobic bacterium
TLDR
Two strains, JW 200 and JW 201, of an extreme thermophilic, non-spore-forming anaerobic bacterium were isolated from alkaline and slightly acidic hot springs located in Yellowstone National Park and the name Thermoanaerobacter ethanolicus gen. nov. Expand
The Fibronectin Type 3-Like Repeat from the Clostridium thermocellum Cellobiohydrolase CbhA Promotes Hydrolysis of Cellulose by Modifying Its Surface
TLDR
The results suggest that Fn31,2 aids the hydrolysis of cellulose by modifying its surface, and this effect is enhanced by the presence of CBDIII, which increases the concentration of Fn 31,2 on the cellulose surface. Expand
Structural basis for the exocellulase activity of the cellobiohydrolase CbhA from Clostridium thermocellum.
TLDR
The detailed analysis of these structures reveals that, while key catalytic residues and overall fold are conserved in this enzyme and those of other family 9 glycoside hydrolases, the active site of GH9_CbhA is blocked off after the -2 subsite, which explains the inability of the active sites of CbhA to accommodate a long cellulose chain and to cut it internally.

  • 1 March 2008
TLDR
Some features of the cellulosome of the anaerobic fungus Orpinomyces sp. Expand
Feruloyl Esterase Activity of the Clostridium thermocellum Cellulosome Can Be Attributed to Previously Unknown Domains of XynY and XynZ
TLDR
The presence of feruloyl esterase in the C. thermocellum cellulosome together with its other hydrolytic activities demonstrates a powerful enzymatic potential of this organelle in plant cell wall decomposition. Expand
Characterization of an Acetyl Xylan Esterase from the Anaerobic Fungus Orpinomyces sp. Strain PC-2
ABSTRACT A 1,067-bp cDNA, designated axeA, coding for an acetyl xylan esterase (AxeA) was cloned from the anaerobic rumen fungusOrpinomyces sp. strain PC-2. The gene had an open reading frame of 939Expand
The complete genome sequence of Moorella thermoacetica (f. Clostridium thermoaceticum).
TLDR
This first genome sequence of an acetogenic bacterium provides important information related to how acetogens engage their extreme metabolic diversity by switching among different carbon substrates and electron donors/acceptors and how they conserve energy by anaerobic respiration. Expand
Cloning and Sequence Analysis of a New Cellulase Gene Encoding CelK, a Major Cellulosome Component of Clostridium thermocellum: Evidence for Gene Duplication and Recombination
TLDR
The data indicate that celK and cbhA in the genome of C. thermocellum have evolved through gene duplication and recombination of domain coding sequences. Expand
Purification and characterization of a new xylanase (APX-II) from the fungus Aureobasidium pullulans Y-2311-1
TLDR
Aureobasidium pullulans Y-2311-1 produced four major xylanases (EC 3.8, 4.0, 7.3, 9.9, and 9.4) and the sequence of the first 68 amino acid residues at the amino terminus showed homology to those of several other xylonases. Expand
