Hydrophobic-cluster analysis was used to characterize a conserved domain located near the C-terminal amino acid sequence of wheat (Triticum aestivum) storage proteins. This domain was transformed into a linear template for a global search for similarities in over 5200 protein sequences. In addition to proteins that had already been found to exhibit homology to wheat storage proteins, a previous...

When spinach (Spinacia oleracea) leaf discs were incubated in a dark anaerobic environment, the chlorophyll fluorescence yield was much increased relative to the aerobic control. Occasionally, the fluorescence yield of the darkened anaerobic samples approached 80% of the maximum fluorescence. The anaerobic incubation period also induced in a leaf disc the capacity to exhibit a low light-mediate...

Abstract Spinach ( Spinacia oleracea L.) is a popular commercial crop that used both fresh and after processing. In terms of nutrition, spinach high in minerals vitamins, particularly ascorbic acid (vitamin C). Lack nutrients the plant may be big issue cultivation, while temperature, water, sunshine also play part growth can impact production. The focus this research was to determine effect NPK...

Results presented in a previous report from this laboratory indicated the presence, in crude extracts from sycamore (Acer pseudoplatanus) and spinach (Spinacea oleracea), of a sucrose synthase (EC 2.4.1.13) showing high affinity for ADP as the glucose acceptor in the sucrose-cleaving reaction. In the present paper we report that the modified enzymatic method previously used to measure sucrose s...

Pyruvate, Mercaptopyruvate, Lemna, Spinacia, Pisum, Chlorella, Synechococcus, Rhodopseudomonas Mercaptopyruvate sulfotransferase activity catalyzes the formation of pyruvate from mercapto­ pyruvate in the presence of suitable reagents as acceptor. It was detected in Lemna minor, Pisum sativum, Spinacia oleracea, Chlorella fusca, Synechococcus 6301, and Rhodopseudomonas palustris. Best activity ...
