Cyclic tetrasaccharide-synthesizing enzymes from Arthrobacter globiformis A19.
A bacterial strain Arthrobacter globiformis A19 producing cyclic tetrasaccharide (CTS) was isolated from soil. The enzymes, 6-alpha-glucosyltransferase (6GT) and 3-alpha-isomaltosyltransferase (IMT), involved in the synthesis of CTS were purified to homogeneity. The molecular and enzymatic properties of IMT from A. globiformis were similar to those of enzymes from Bacillus globisporus C11 and N...
متن کاملRoles of Serine 101, Histidine 310 and Valine 464 in the Reaction Catalyzed by Choline Oxidase from Arthrobacter Globiformis
The enzymatic oxidation of choline to glycine betaine is of interest because organisms accumulate glycine betaine intracellularly in response to stress conditions, as such it is of potential interest for the genetic engineering of crops that do not naturally possess efficient pathways for the synthesis of glycine betaine, and for the potential development of drugs that target the glycine betain...
متن کاملRegulation of hepatic L-serine dehydratase and L-serine-pyruvate aminotransferase in the developing neonatal rat.
1. The activities of l-serine dehydratase and l-serine-pyruvate aminotransferase were determined in rat liver during foetal and neonatal development. 2. l-Serine-pyruvate aminotransferase activity begins to develop in late-foetal liver, increases rapidly at birth to a peak during suckling and then decreases at weaning to the adult value. 3. l-Serine dehydratase activity is very low prenatally, ...
متن کاملIsolation and characterization of a bacteriophage of Arthrobacter globiformis.
A bacteriophage which reproduces on Arthrobacter globiformis ATCC 8010 was isolated from soil. This bacteriophage, designated phiAG8010, propagates either in soft agar or broth cultures of the host. Because of a slow adsorption rate, neither the latent period nor burst size was determined. The mature virion belongs to Bradley's group B and exhibits a hexagonal head measuring 69 nm (length) by 6...
متن کاملInduction of L-serine dehydratase in Aeromonas punctata.
L-Serine dehydratase (SD) was produced to the extent of only 0·04 international unit (iu) per mg dry weight by Aeromollas pUllctata NRRL B-928 when grown on a chemically defined medium. Addition of 2% (w/v) L-serine to this medium increased SD ten-fold or more, indicating a significant inductive effect. o-Serine was toxic to the organism, making weights and enzyme titres uncertain, but DL-serin...
