SYSTEMATIC NAME
IUBMB Comments
betaine-aldehyde:NAD+ oxidoreductase
In many bacteria, plants and animals, the osmoprotectant betaine is synthesized in two steps: (1) choline to betaine aldehyde and (2) betaine aldehyde to betaine. This enzyme is involved in the second step and appears to be the same in plants, animals and bacteria. In contrast, different enzymes are involved in the first reaction. In plants, this reaction is catalysed by EC 1.14.15.7 (choline monooxygenase), whereas in animals and many bacteria it is catalysed by either membrane-bound EC 1.1.99.1 (choline dehydrogenase) or soluble EC 1.1.3.17 (choline oxidase) [5]. In some bacteria, betaine is synthesized from glycine through the actions of EC 2.1.1.156 (glycine/sarcosine N-methyltransferase) and EC 2.1.1.157 (sarcosine/dimethylglycine N-methyltransferase).

Results demonstrate that accumulation of glycine betaine in vivo in the chloroplast in tobacco plants by introducing the BADH gene for betaine aldehyde dehydrogenase from spinach resulted in increased tolerance of growth of young seedlings to salt stress. Furthermore results demonstrate that accumulation of glycine betaine in vivo leads to increased tolerance of CO2 assimilation to salt stress.

dominant Badh2 allele encoding betaine aldehyde dehydrogenase inhibits the synthesis of 2-acetyl-1-pyrroline, a potent flavor component in rice fragrance. Because the absence of BADH2 protein results in fragrance, this suggests that Badh2 is not directly involved in biosynthesis. Alternative possibilities to explain the effect of BADH2 are that the BADH2 enzyme is involved in a competing pathway in which one of the 2-acetyl-1-pyrroline precursors serves as a BADH2 substrate or that BADH2 participates in 2-acetyl-1-pyrroline catabolism. The intact 503 amino acid BADH2 encoded by the complete Badh2 gene inhibits 2-acetyl-1-pyrroline biosynthesis by converting 4-aminobutyraldehyde to gamma-aminobutyric acid, whereas the absence of BADH2 due to nonfunctional badh2 alleles results in AB-ald accumulation and thus turns on the pathway toward 2-acetyl-1-pyrroline biosynthesis.

dominant Badh2 allele encoding betaine aldehyde dehydrogenase inhibits the synthesis of 2-acetyl-1-pyrroline, a potent flavor component in rice fragrance. Because the absence of BADH2 protein results in fragrance, this suggests that Badh2 is not directly involved in biosynthesis. Alternative possibilities to explain the effect of BADH2 are that the BADH2 enzyme is involved in a competing pathway in which one of the 2-acetyl-1-pyrroline precursors serves as a BADH2 substrate or that BADH2 participates in 2-acetyl-1-pyrroline catabolism. The intact 503 amino acid BADH2 encoded by the complete Badh2 gene inhibits 2-acetyl-1-pyrroline biosynthesis by converting 4-aminobutyraldehyde to gamma-aminobutyric acid, whereas the absence of BADH2 due to nonfunctional badh2 alleles results in AB-ald accumulation and thus turns on the pathway toward 2-acetyl-1-pyrroline biosynthesis.

CAS 97-77-8, reaction of disulfiram with protein thiol groups by formation of a mixed disulfide or formation of an intra-molecular disulfide resulting in conformational changes. Inactivation under pseudo-first order conditions occurs in a time- and dose-dependent manner. In the absence of disulfiram, but in the presence of 2% methanol as DSF vehicle, no changes in enzymatic activities are observed. Using a DSF concentration range 10-30 microM, inactivation kinetics were biphasic with rate constants differing in one order of magnitude, and inactivation partial. The residual activity at infinite time, decreases as the disulfiram concentrations increases, reaching a value near zero at 30 microM disulfiram, whereas the amplitude of the two inactivation phases increases, each one reaching about 50% of initial activity at 30 microM disulfiram.
