invertase/glycine max

Invertases are essential enzymes that irreversibly catalyze the cleavage of sucrose into glucose and fructose. Cell wall invertase (CWI) and vacuolar invertase (VI) are glycosylated proteins and exert fundamental roles in plant growth as well as in response to environmental cues. As yet,

Cell wall invertase (CWI) and vacuolar invertase (VI) play multiple functions in plant growth. As well as depending on transcriptional and post-transcriptional regulation, there is growing evidence that CWI and VI are also subject to post-translational control by small inhibitory proteins. Despite

The specific activities of acid and alkaline invertases (beta-d-fructofuranoside fructohydrolase, EC 3.2.1.26), sucrose synthase (UDPglucose: d-fructose 2-alpha-d-glucosyltransferase, EC 2.4.1.13), hexokinase (ATP: d-hexose 6-phosphotransferase, EC 2.7.1.1), and fructokinase (ATP: d-fructose

Alkaline invertase from sprouting soybean (Glycine max) hypocotyls was purified to apparent electrophoretic homogeneity by consecutive use of DEAE-cellulose, green 19 dye, and Cibacron blue 3GA dye affinity chromatography. This protocol produced about a 100-fold purification with about a 11% yield.

The relative contributions of invertase and sucrose synthase to initial cleavage of phloem-imported sucrose was calculated for sink leaves of soybean (Glycine max L. Merr cv Wye) and sugar beet (Beta vulgaris L. monohybrid). Invertase from yeast hydrolyzed sucrose 4200 times faster than

Characterization of sugar content and enzyme activity in germinating soybean (Glycine max L. Merrell) seeds led to the discovery of sorbitol accumulating in the axes during germination. The identity of sorbitol was confirmed by relative retention times on high-performance liquid chromatography and

The effects of K-deficiency on carbon exchange rates (CER), photosynthate partitioning, export rate, and activities of key enzymes involved in sucrose metabolism were studied in soybean (Glycine max [L.] Merr.) leaves. The different parameters were monitored in mature leaves that had expanded prior

Crude, Sephadex-filtered extracts of soybean (Glycine max (L.) Merr.) root nodules contained invertase (E.C. 3.2.1.26) activity with pH optima at 5.4 and 7.8, α,α-trehalase (E.C. 3.2.1.28) activity with pH optima at 3.8 and 6.6, and maltase (E.C. 3.2.1.20) activity with a broad pH optimum between

With pot experiment, two soybean (Glycine max) varieties, Jindou 21 (drought-tole-rant) and Xudou 22 (drought-sensitive), were used to examine the effects of α-naphthaleneacetic acid (NAA) on carbon metabolism of soybean under drought stress at flowering stage. The results showed that under drought

In the present study, leaves of different plant species were girdled by the hot wax collar method to prevent export of assimilates. Photosynthetic activity of girdled and control leaves was evaluated 3 to 7 days later by two methods: (a) carbon exchange rate (CER) of attached leaves was determined
