Assessment of the dietary amino acid profiles and the relative biomarkers for amino acid balance in the low-protein diets for broiler chickens [PDF]
Journal of Animal Science and BiotechnologyBackground Research on low-protein-level diets has indicated that even though the profiles of essential amino acids (EAAs) follow the recommendation for a normal-protein-level diet, broilers fed low-protein diets failed to achieve productive performance ...

Coenzyme- and His-tag-induced crystallization of octopine dehydrogenase [PDF]
Acta Crystallographica Section F: Structural Biology Communications, 2008 Over the last decade, protein purification has become more efficient and standardized through the introduction of affinity tags. The choice and position of the tag, however, can directly influence the process of protein crystallization. Octopine dehydrogenase (OcDH) without a His tag and tagged protein constructs such as OcDH-His(5) and OcDH-LEHis(6 ...

Effects of Octopine on the Serum Cholesterol Level in Rats
Bioscience, Biotechnology and Biochemistry, 1996 The effects of dietary octopine, which is one of the major extractive component of marine molluscs, on the level of serum and liver cholesterol of rats fed with cholesterol-enriched or cholesterol-free diets were investigated. Dietary supplementation with 1.5% octopine in a cholesterol-enriched diet significantly decreased the serum total- and VLDL+LDL-

Competition of Octopine-Catabolizing Pseudomonas spp. and Octopine-Type Agrobacterium tumefaciens for Octopine in Chemostats [PDF]
Applied and Environmental Microbiology, 1990 The ability of two octopine-catabolizing Pseudomonas spp. and two virulent octopine-type Agrobacterium tumefaciens to compete for substrates has been examined in chemostats. In dual cultures with octopine or glutamate as the limiting carbon or nitrogen source, Pseudomonas ...

European Journal of Biochemistry, 1972 The amino acid composition of octopine dehydrogenase from muscles of Pecten maximus was determined. The calculate dpartial specific volume of 0.74 allowed us to evaluate the molecular weight of the enzyme as 38000.It is concluded that this enzyme consists of a single polypeptide chain on the basis of the molecular weight determined from equilibrium ...

Changes to coral health and metabolic activity under oxygen deprivation [PDF]
PeerJ, 2016 On Hawaiian reefs, the fast-growing, invasive algae Gracilaria salicornia overgrows coral heads, restricting water flow and light, thereby smothering corals. Field data shows hypoxic conditions (dissolved oxygen (DO2) < 2 mg/L) occurring underneath algal

Characterization of Flavin-Containing Opine Dehydrogenase from Bacteria. [PDF]
PLoS ONE, 2015 Opines, in particular nopaline and octopine, are specific compounds found in crown gall tumor tissues induced by infections with Agrobacterium species, and are synthesized by well-studied NAD(P)H-dependent dehydrogenases (synthases), which catalyze the ...

Isolation and Characterization of Agrobacterium tumefaciens Mutants Affected in the Utilization of Octopine, Octopinic Acid and Lysopine [PDF]
Journal of General Microbiology, 1976 Using an enrichment procedure, mutant strains of Agrobacterium tumefaciens were isolated that lacked the ability to utilize octopine as a nitrogen source. Of 55 such isolates, 44 were unable to utilize several amino acids; the remaining 11 strains were altered solely in their ability to utilize octopine, octopinic acid and lysopine.
