Studies on Malic Dehydrogenese Isozyme

Studies on Malic Enzyme from Hymenolepis Diminuta

Structural studies of the pigeon cytosolic NADP(+)-dependent malic enzyme.

Malic enzymes are widely distributed in nature, and have important biological functions. They catalyze the oxidative decarboxylation of malate to produce pyruvate and CO(2) in the presence of divalent cations (Mg(2+), Mn(2+)). Most malic enzymes have a clear selectivity for the dinucleotide cofactor, being able to use either NAD(+) or NADP(+), but not both. Structural studies of the human mitoc...

Isozyme Studies of Bark Beetle Population Genetics and Systematics1

Electrophoretic analysis was used extensively in the 1970's to estimate genetic relationships among populations, species, and closely related genera of many different plants and animals, including many insect groups. Some of the first electrophoretic work on bark beetles was done by Anderson and others (1979), Anderson and others (1983), Florence and Kulhavy (1981), Florence and others (1982), ...

Koa:A Decade of Growth ~ Isozyme Studies of Genetic Variability

Little is known about genetic variation and geographic patterns of diversity of Acacia koa. We analyzed diversity using laboratory studies of enzymes. Wide samples of koa possess significant variation in six enzyme genes; several genes have alleles in intermediate frequencies. The variable genes have average expected heterozygosity of 0.41; this indicates that koa has significant levels of gene...

Malic Acid & Metabolic Acidosis

Label-MMAcid-Rev030410 BACKGROUND Ruminants are animals that have multiple stomachs to allow consumption and digestion of fibrous feedstuffs. Key to this digestive process is the bacterial breakdown of the fiber in the first stomach or rumen. The bacterial balance in the rumen can shift, allowing the ruminant to adapt to different diets. Ruminal bacteria convert fiber into lactate and volatile ...
