Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)
Enzymes of the isomerase class that catalyze the transfer of acyl-, phospho-, amino- or other groups from one position within a molecule to another. EC 5.4.
Enzymes that catalyze the breakage of a carbon-oxygen bond leading to unsaturated products via the removal of water. EC 4.2.1.
Purine or pyrimidine bases attached to a ribose or deoxyribose. (From King & Stansfield, A Dictionary of Genetics, 4th ed)
Any of the infectious diseases of man and other animals caused by species of MYCOBACTERIUM.
MYCOBACTERIUM infections of the lung.
Tuberculosis resistant to chemotherapy with two or more ANTITUBERCULAR AGENTS, including at least ISONIAZID and RIFAMPICIN. The problem of resistance is particularly troublesome in tuberculous OPPORTUNISTIC INFECTIONS associated with HIV INFECTIONS. It requires the use of second line drugs which are more toxic than the first line regimens. TB with isolates that have developed further resistance to at least three of the six classes of second line drugs is defined as EXTENSIVELY DRUG-RESISTANT TUBERCULOSIS.
A species of gram-positive, aerobic bacteria that produces TUBERCULOSIS in humans, other primates, CATTLE; DOGS; and some other animals which have contact with humans. Growth tends to be in serpentine, cordlike masses in which the bacilli show a parallel orientation.
Tuberculosis resistant to ISONIAZID and RIFAMPIN and at least three of the six main classes of second-line drugs (AMINOGLYCOSIDES; polypeptide agents; FLUOROQUINOLONES; THIOAMIDES; CYCLOSERINE; and PARA-AMINOSALICYLIC ACID) as defined by the CDC.
Acquiring information from a patient on past medical conditions and treatments.
The ability of bacteria to resist or to become tolerant to several structurally and functionally distinct drugs simultaneously. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS).
A mitochondrial protein consisting of four alpha-subunits and four beta-subunits. It contains enoyl-CoA hydratase, long-chain-3-hydroxyacyl-CoA dehydrogenase, and acetyl-CoA C-acyltransferase activities and plays an important role in the metabolism of long chain FATTY ACIDS.
The beta subunit of mitochondrial trifunctional protein that contains acetyl-CoA C-acyltransferase activity. There are four of these beta subunits in each trifunctional protein complex.
The alpha subunit of mitochondrial trifunctional protein. It contains both enoyl-CoA hydratase activity (EC and long-chain-3-hydroxyacyl-CoA dehydrogenase activity (EC There are four of these alpha subunits in each mitochondrial trifunctional protein molecule.
Enzyme that catalyzes the final step of fatty acid oxidation in which ACETYL COA is released and the CoA ester of a fatty acid two carbons shorter is formed.
An NAD-dependent 3-hydroxyacyl CoA dehydrogenase that has specificity for acyl chains containing 8 and 10 carbons.
Enzymes that reversibly catalyze the oxidation of a 3-hydroxyacyl CoA to 3-ketoacyl CoA in the presence of NAD. They are key enzymes in the oxidation of fatty acids and in mitochondrial fatty acid synthesis.
Small chromosomal proteins (approx 12-20 kD) possessing an open, unfolded structure and attached to the DNA in cell nuclei by ionic linkages. Classification into the various types (designated histone I, histone II, etc.) is based on the relative amounts of arginine and lysine in each.
Enzymes that catalyze acyl group transfer from ACETYL-CoA to HISTONES forming CoA and acetyl-histones.
The repeating structural units of chromatin, each consisting of approximately 200 base pairs of DNA wound around a protein core. This core is composed of the histones H2A, H2B, H3, and H4.
The material of CHROMOSOMES. It is a complex of DNA; HISTONES; and nonhistone proteins (CHROMOSOMAL PROTEINS, NON-HISTONE) found within the nucleus of a cell.
Formation of an acetyl derivative. (Stedman, 25th ed)
Enzymes catalyzing the transfer of an acetyl group, usually from acetyl coenzyme A, to another compound. EC 2.3.1.
A division of predominantly marine EUKARYOTA, commonly known as brown algae, having CHROMATOPHORES containing carotenoid PIGMENTS, BIOLOGICAL. ALGINATES and phlorotannins occur widely in all major orders. They are considered the most highly evolved algae because of their well-developed multicellular organization and structural complexity.
A family of DNA plant viruses that infect eukaryotic algae.
One of the enzymes active in the gamma-glutamyl cycle. It catalyzes the synthesis of glutathione from gamma-glutamylcysteine and glycine in the presence of ATP with the formation of ADP and orthophosphate. EC
Multicellular marine macroalgae including some members of red (RHODOPHYTA), green (CHLOROPHYTA), and brown (PHAEOPHYTA) algae. They are widely distributed in the ocean, occurring from the tide level to considerable depths, free-floating (planktonic) or anchored to the substratum (benthic). They lack a specialized vascular system but take up fluids, nutrients, and gases directly from the water. They contain CHLOROPHYLL and are photosynthetic, but some also contain other light-absorbing pigments. Many are of economic importance as FOOD, fertilizer, AGAR, potash, or source of IODINE.
A heavy metal trace element with the atomic symbol Cu, atomic number 29, and atomic weight 63.55.
Poly-glutathione peptides composed of (Glu-Cys)n-Gly where n is two to seven. They are biosynthesized by glutathione gamma-glutamylcysteinyltransferase and are found in many PLANTS; YEASTS; and algae. They sequester HEAVY METALS.
The reproductive cells of plants.
