A genus of aerobic or facultatively anaerobic BACTERIA, in the family Cellulomonadaceae. It is found in the SOIL and capable of hydrolyzing CELLULOSE.

A gram-positive, non-spore-forming group of bacteria comprising organisms that have morphological and physiological characteristics in common.

An order of gram-positive, primarily aerobic BACTERIA that tend to form branching filaments.

An exocellulase with specificity for the hydrolysis of 1,4-beta-glucosidic linkages of 1,4-beta-D-glucans resulting in successive removal of GLUCOSE units.

A polysaccharide with glucose units linked as in CELLOBIOSE. It is the chief constituent of plant fibers, cotton being the purest natural form of the substance. As a raw material, it forms the basis for many derivatives used in chromatography, ion exchange materials, explosives manufacturing, and pharmaceutical preparations.

An endocellulase with specificity for the hydrolysis of 1,4-beta-glucosidic linkages in CELLULOSE, lichenin, and cereal beta-glucans.

An exocellulase with specificity for a variety of beta-D-glycoside substrates. It catalyzes the hydrolysis of terminal non-reducing residues in beta-D-glucosides with release of GLUCOSE.

A xylosidase that catalyses the random hydrolysis of 1,3-beta-D-xylosidic linkages in 1,3-beta-D-xylans.

A genus of aerobic, gram-negative, motile, slightly curved, rod-shaped bacteria. (From Bergey's Manual of Determinative Bacteriology, 9th ed)

A group of enzymes that catalyze the hydrolysis of alpha- or beta-xylosidic linkages. EC 3.2.1.8 catalyzes the endo-hydrolysis of 1,4-beta-D-xylosidic linkages; EC 3.2.1.32 catalyzes the endo-hydrolysis of 1,3-beta-D-xylosidic linkages; EC 3.2.1.37 catalyzes the exo-hydrolysis of 1,4-beta-D-linkages from the non-reducing termini of xylans; and EC 3.2.1.72 catalyzes the exo-hydrolysis of 1,3-beta-D-linkages from the non-reducing termini of xylans. Other xylosidases have been identified that catalyze the hydrolysis of alpha-xylosidic bonds.

A large group of rod-shaped bacteria that retains the crystal violet stain when treated by Gram's method.

A plant genus of the family ULMACEAE that is susceptible to Dutch elm disease which is caused by the ASCOMYCOTA fungus, Ophiostoma.

Polysaccharides consisting of xylose units.

An exocellulase with specificity for 1,3-beta-D-glucasidic linkages. It catalyzes hydrolysis of beta-D-glucose units from the non-reducing ends of 1,3-beta-D-glucans, releasing GLUCOSE.

A disaccharide consisting of two glucose units in beta (1-4) glycosidic linkage. Obtained from the partial hydrolysis of cellulose.

Enzymes which catalyze the endohydrolysis of 1,4-beta-D-xylosidic linkages in XYLANS.

DNA sequences encoding RIBOSOMAL RNA and the segments of DNA separating the individual ribosomal RNA genes, referred to as RIBOSOMAL SPACER DNA.

Constituent of 30S subunit prokaryotic ribosomes containing 1600 nucleotides and 21 proteins. 16S rRNA is involved in initiation of polypeptide synthesis.

An exocellulase with specificity for the hydrolysis of 1,4-beta-D-glucosidic linkages in CELLULOSE and cellotetraose. It catalyzes the hydrolysis of terminal non-reducing ends of beta-D-glucosides with release of CELLOBIOSE.

The relationships of groups of organisms as reflected by their genetic makeup.

Former kingdom, located on Korea Peninsula between Sea of Japan and Yellow Sea on east coast of Asia. In 1948, the kingdom ceased and two independent countries were formed, divided by the 38th parallel.

Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.

Genes, found in both prokaryotes and eukaryotes, which are transcribed to produce the RNA which is incorporated into RIBOSOMES. Prokaryotic rRNA genes are usually found in OPERONS dispersed throughout the GENOME, whereas eukaryotic rRNA genes are clustered, multicistronic transcriptional units.

Deoxyribonucleic acid that makes up the genetic material of bacteria.
