Anaerobic induction of alanine aminotransferase in barley root tissue.
Alanine aminotransferase, otherwise called glutamate-pyruvate aminotransferase (GPT), activity increases up to fourfold during several days of anaerobic induction in barley (Hordeum vulgare L.) roots, reaching a maximum activity of 13 international units per gram fresh weight. This increase in activity paralleled the increase in alcohol dehydrogenase activity in the same root tissue. Upon retur...
متن کاملAmino- and carboxyl-terminal analyses of hepatoma lactate dehydrogenase isozymes.
The M4 isozyme of lactate dehydrogenase was purified to homogeneity from normal rat liver and from two Morris hepatomas (7777 and 7793). Amino-terminal analyses with fluorodinitrobenzene failed to detect the presence of free amino-terminal residues in each enzyme studied. Each enzyme contained between 3.7 and 4.1 moles of protein-bound acetyl groups per mole of enzyme. The amino-terminal peptid...
متن کاملGenetic Evidence for the Subunit Structure of Lactate Dehydrogenase Isozymes.
The lactate dehydrogenases commonly occur in from one to five molecular forms (isozymes) in the various tissues of an animal species.' By means of zone electrophoresis, characteristic patterns of these isozymes may be demonstrated in each tissue. In adult animals, most tissues contain all five isozymes but in different proportions. Usually, heart muscle exhibits principally the first, or most n...
متن کاملIntracellular location and possible function of malic dehydrogenase isozymes from young maize root tissue.
It is known that there is a separation, i.e., compartmentation of organic acids in young maize tissue (11) and that the organic acid prodtucts (specifically malic acid) of CO, fixation are not in complete equilibriuim with mitochondrial pools (9, 10). Thus, there are at least 2 essentially separate metabolic pools of organic acids. Previous work with corn root tips led tus to postulate a metabo...
متن کاملTissue distribution of mammalian lactate dehydrogenase isoenzymes.
system of Jervis [7] is used here.) Previous electrophoretic examination of the LDH of most other plants was carried out with extracts from leaves [1,2j. Such a study of potato leaves would not have revealed the existence of isoenzymic forms in this species. We have, therefore, examined extracts from various regions of a number of plants: roots, stem-base, upper stems, leaves and any special ti...
