Barley (Hordeum vulgare) oxalate oxidase is a manganese-containing enzyme.
Oxalate oxidase (EC 1.2.3.4) catalyses the conversion of oxalate and dioxygen into CO(2) and H(2)O(2). The barley (Hordeum vulgare) seedling root enzyme was purified to homogeneity and shown by metal analysis and EPR spectroscopy to contain Mn(II) at up to 0.80 atom per subunit. The involvement of Mn and neither flavin, Cu nor Fe in the direct conversion of dioxygen to H(2)O(2) makes oxalate ox...
متن کاملLysine Catabolism in Barley (Hordeum vulgare L.).
Lysine catabolism in seedlings of barley (Hordeum vulgare L. var. Emir) was studied by direct injection of the following tracers into the endosperm of the seedlings: aspartic acid-3-(14)C, 2-aminoadipic acid-1-(14)C, saccharopine-(14)C, 2,6-diaminopimelic acid-1-(7)-(14)C, and lysine-1-(14)C. Labeled saccharopine was formed only after the administration of either labeled 2,6-diaminopimelic acid...
متن کاملAllelopathic Plants. 19. Barley (Hordeum vulgare L)
Barley is integrated with other crops to inhibit weed growth, through allelopathic interactions. Effects of barley on growth of other crops, weeds and autotoxicity among cultivars result primarily from allelopathy mediated by allelochemicals released from plant components and/or exuded from living roots. A limited number of allelochemicals are identified that contributes to allelopathic effecti...
متن کاملFurther Characterization of Calmodulin from the Monocotyledon Barley (Hordeum vulgare).
We report here that calmodulin isolated from the monocotyledon barley is indistinguishable by a variety of criteria from calmodulin isolated from the dicotyledon spinach. In contrast to previous reports, we find that barley (Hordeum vulgare) calmodulin has an amino acid composition similar to that of vertebrate and spinach calmodulins, including the presence of a single trimethyllysinyl residue...
متن کاملIdentification of a Phytase Gene in Barley (Hordeum vulgare L.)
BACKGROUND Endogenous phytase plays a crucial role in phytate degradation and is thus closely related to nutrient efficiency in barley products. The understanding of genetic information of phytase in barley can provide a useful tool for breeding new barley varieties with high phytase activity. METHODOLOGY/PRINCIPAL FINDINGS Quantitative trait loci (QTL) analysis for phytase activity was condu...
