(4) The distribution of total AAT activity (tAAT = cAAT + mAAT) and of mAAT activity correlated well (r = 0.88-0.91) with the distribution of MDH activity.
(5) These results suggest that testosterone stimulated mAAT activity by induction of pmAAT mRNA.
(6) Phentolamine did not alter the noradrenaline effect on either mAAT or cAAT; it decreased significantly the free form of the mAAT activity only.

(8) The pmAAT mRNA induction occurred 30 min after testosterone treatment and was maximal by 1.5 h. Prostatic mAAT activity was also induced by testosterone with a 1-2 h lag period.
(9) Distributions of activity of the cytosolic (cAAT) and mitochondrial (mAAT) isoenzymes of aspartate aminotransferase and of malate dehydrogenase (MDH) were determined in guinea pig retinal layers.
(10) This continues to support our proposal that testosterone regulates prostate citrate production via a stimulatory effect on mAAT which results in increased mitochondrial synthesis of citrate from aspartate.
(11) For the quinonoid complex with erythro-3-hydroxyaspartate, the tilt angles were found to be 63 degrees in cAAT and 53 degrees in mAAT.
(12) The effects of testosterone on mitochondrial aspartate aminotransferase (mAAT) synthesis in rat ventral prostate was investigated.
(13) cAAT was highest in the photoreceptor inner segments, inner nuclear layer and inner plexiform layer; mAAT was highest in the inner segments.
(14) cAAT activity was also highest in the inner segments, but the difference between the activity in the inner segments and the other layers was not nearly as great as with mAAT.
(15) Cytosolic and mitochondrial pig aspartate aminotransferases (cAAT and mAAT) and chicken cAAT were oriented in a compressed slab of polyacrylamide gel.
(16) Maat medium improved the purity and longevity of neuronal cultures.

(18) Insertion of an 18-nucleotide-long poly(G) tract into the 3'-terminal untranslated region of yeast phosphoglycerate kinase (PGK1) mRNA increases its chemical half-life by about a factor of 2 (P. Vreken, R. Van der Veen, V. C. H. F. de Regt, A. L. de Maat, R. J. Planta, and H. A. Raué, Biochimie 73:729-737, 1991).
(19) Prolactin (PRL) has been reported to stimulate citrate production and the activity of mitochondrial aspartate aminotransferase (mAAT) and its precursor form pmAAT in prostate epithelial cells.
(20) The differences in the coenzyme tilt angles between cAAT and mAAT might be linked to catalytic peculiarities of the isoenzymes.
Malt
Definition:
(n.) Barley or other grain, steeped in water and dried in a kiln, thus forcing germination until the saccharine principle has been evolved. It is used in brewing and in the distillation of whisky.
(a.) Relating to, containing, or made with, malt.
(v. t.) To make into malt; as, to malt barley.
(v. i.) To become malt; also, to make grain into malt.
Example Sentences:
(1) Translation of the tnsC ORF reveals strong homology to a consensus sequence for nucleotide binding sites as well as a region of similarity to a transcriptional activator (MalT).

(4) The promoters of all of these operons are strictly controlled by the activator protein MalT.
(5) Investigations on 85Sr containing malt extract broth Aspergillus fumigatus cultures revealed that fungal hyphas did not contain the major proportion of radioactivity, but culture filtrates did, and suggested that a fungal metabolite may be responsible for radiostrontium binding.
(6) Absurdly, the shops lack local staples – sugar, milk, flour – but are well stocked with subsidised imports such as single-malt whisky and Italian panettone.
(7) The primary structure of malt carboxypeptidase III has been determined.
(8) The results are discussed in terms of the proposed immune surveillance functions attributed to immunocompetent cells in situ according to the mucosal associated lymphatic tissue (MALT) concept.
(9) Water solutions of Tris maltolate aluminium(III) (Al(malt)3) and aluminium lactate (Al(lac)3) are also effective but the dose-response behavior is less pronounced.
