Abstract Two soluble hexokinases and a particulate hexokinase have been separated and partially purified from spinach leaves. One of the soluble hexokinases showed a high affinity for glucose ( K m = 63 μM) which was far greater than that for fructose ( K m = 9.1 mM).

Spinach protein factor and chlorophyllase
Planta, 19721. Spinach leaves contain a "Spinach Protein Factor" (SPF) which increases light sensitivity of colloidal chlorophylls in aqueous solution (Terpstra, 1967). SPF activity, measured in different fractions of spinach-leaf acetone-powder extracts obtained by gel filtration on DEAE- and CM-Sephadex, runs parallel with chlorophyllase activity.

The aggregation states of spinach phosphoribulokinase
Planta, 1990Phosphoribulokinase (PRK; EC 2.1.7.19) is active in illuminated chloroplasts and inactive in darkened chloroplasts. This regulatory mechanism is mediated by thioredoxin-dependent reduction of a kinase disulfide in vivo. Extracts of spinach (Spinacia oleracea L.) leaves in the presence of 10 mM dithiothreitol contain a single 80-kDa form of PRK as ...

ATP-sulphurylase in spinach leaves
Biochimica et Biophysica Acta (BBA) - Enzymology, 1970ATP-sulphurylase (adenosine triphosphate-sulfate adenylyltransferase, EC 2.7.7.4) in spinach leaves was found to be associated with chloroplast fractions prepared in non-aqueous solvents, since the enzyme leached out of the chloroplasts during their isolation in isotonic buffer systems. A new assay using the luciferin-luciferase enzyme system of the

Abstract Phenolase activity is not found in germinating spinach embryos, but it appears in the radicles when the vascular tissues have developed, and then increases progressively. Unlike the two phenolases detected earlier in the chloroplasts, the root enzyme is a single protein with higher MW occurring both in 3000 g precipitate and 28 000 g ...

DEVELOPMENT AND COMPOSITION OF THE SPINACH OVULE
Acta Botanica Neerlandica, 1980SUMMARY The ultrastructure and histochemistry of the developing spinach ovule have been examined. The development and differentiation of the integuments, nucellus and female gametophyte results in an ortho-amphitropous organisation of the ovule. In the nucellus four parts can be distinguished: the conductive part, the original chalazal part, the ...

New Zealand spinach is native to the islands of New Zealand, as many coastal parts of New Zealand have been the homes to this creeping plant prior to the colonial period. For more than 200 years, it was the only exported vegetable native to New Zealand or Australia. New Zealand spinach is nutritionally almost similar to common spinach.
