[Alcohol dehydrogenase (ADH) in yeast cells. I. Cytoplasmic, mitochondrial and nuclear ADH in Saccharomyces carlsbergensis and Kluyveromyces fragilis]. 1976

W Künkel, and R May

When grown in a medium containing lactat, Saccharomyces carlsbergensis produces 5 times more ground-plasmatic ADH than Kluyveromyces fragilis. Upon gelectrophoresis, K. fragilis exhibits 7 bands while S. carlsbergensis shows only one. In a polyacrylamid gradient, the ADH's of both strains yield one band, the position of which corresponds to a molecular weight of about 160 000 D. In cell homogenates and mitochondrial fractions of S. carlsbergensis treated with ultrasound, an ADH is detected which exhibits 3 subbands and a molecular weight greater than 1 Megadalton. This ADH does not occur in K. fragilis. Mitochondrial fractions from K. fragilis contain an ADH, the electrophoretical mobility of which is identical to that of the ADH of the groundplasma. Nuclei of S. carlsbergensis also possess ADH whereas those of K. fragilis probably do not.

UI	MeSH Term	Description	Entries
D007773	Lactates	Salts or esters of LACTIC ACID containing the general formula CH3CHOHCOOR.
D008928	Mitochondria	Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes.

D008970	Molecular Weight	The sum of the weight of all the atoms in a molecule.	Molecular Weights,Weight, Molecular,Weights, Molecular
D002467	Cell Nucleus	Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)	Cell Nuclei,Nuclei, Cell,Nucleus, Cell

D004718	Saccharomycetales	An order of fungi in the phylum Ascomycota that multiply by budding. They include the telomorphic ascomycetous yeasts which are found in a very wide range of habitats.

D000429	Alcohol Oxidoreductases	A subclass of enzymes which includes all dehydrogenases acting on primary and secondary alcohols as well as hemiacetals. They are further classified according to the acceptor which can be NAD+ or NADP+ (subclass 1.1.1), cytochrome (1.1.2), oxygen (1.1.3), quinone (1.1.5), or another acceptor (1.1.99).

D001203	Ascomycota	A phylum of fungi which have cross-walls or septa in the mycelium. The perfect state is characterized by the formation of a saclike cell (ascus) containing ascospores. Most pathogenic fungi with a known perfect state belong to this phylum.	Ascomycetes,Cochliobolus,Sclerotinia,Ascomycete,Ascomycotas,Sclerotinias

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
