An assay for beta-alanine transaminase activity in extracts of Drosophila melanogaster has been developed. By use of this assay, the levels of beta-alanine transaminase activity in several strains of flies has been examined as a function of developmental age. The black mutation shows elevated levels of activity compared to wild type, while suppressor of black strains show decreased levels compared to wild type.

D007700 Kinetics The rate dynamics in chemical or physical systems.
D010858 Pigmentation Coloration or discoloration of a part by a pigment. Pigmentations
D004331 Drosophila melanogaster A species of fruit fly frequently used in genetics because of the large size of its chromosomes. D. melanogaster,Drosophila melanogasters,melanogaster, Drosophila
D005969 Glutamate Dehydrogenase An enzyme that catalyzes the conversion of L-glutamate and water to 2-oxoglutarate and NH3 in the presence of NAD+. (From Enzyme Nomenclature, 1992) EC 1.4.1.2. Dehydrogenase, Glutamate
D000612 4-Aminobutyrate Transaminase An enzyme that converts brain gamma-aminobutyric acid (GAMMA-AMINOBUTYRIC ACID) into succinate semialdehyde, which can be converted to succinic acid and enter the citric acid cycle. It also acts on beta-alanine. EC 2.6.1.19.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D015091 beta-Alanine An amino acid formed in vivo by the degradation of dihydrouracil and carnosine. Since neuronal uptake and neuronal receptor sensitivity to beta-alanine have been demonstrated, the compound may be a false transmitter replacing GAMMA-AMINOBUTYRIC ACID. A rare genetic disorder, hyper-beta-alaninemia, has been reported. 3-Aminopropionic Acid,beta-Alanine Hydrochloride,beta-Alanine, Calcium Salt (2:1),beta-Alanine, Monopotassium Salt,beta-Alanine, Monosodium Salt,3 Aminopropionic Acid,Hydrochloride, beta-Alanine,beta Alanine,beta Alanine Hydrochloride,beta Alanine, Monopotassium Salt,beta Alanine, Monosodium Salt
