Hydroperoxide lyase (HPLS) activity in soybean (Glycine max) seed/seedlings, leaves, and chloroplasts of leaves required detergent solubilization for maximum in vitro activity. On a per milligram of protein basis, more HPLS activity was found in leaves, especially chloroplasts, than in seeds or

A novel lipoxygenase (BLOX) was purified from black soybean (Glycine max (L.) Merr.), and its catalytic properties were characterized. The molecular weight of BLOX was 101 kDa and its unique heterodimeric structure with two different subunits of molecular weight 46 kDa and 55 kDa was elucidated. The

This work reports on the use of a three dimensional separation system to enhance metalloprotein information when considering soybean seeds. Separations using size exclusion chromatography (SEC) allowed identification of three metal fractions. Following an anion exchange (AEX) chromatographic

The appearance and subsequent disappearance of lipoxygenase activity at pH 6.8 in germinated cotyledons of soybean (Glycine max [L.]) was shown using a variant soybean cultivar (Kanto 101) that lacks the two lipoxygenase isozymes, L-2 and L-3, that are present in dry seeds of a normal soybean

In previous work with soybean (Glycine max), it was reported that the initial product of 3Z-nonenal (NON) oxidation is 4-hydroperoxy-2E-nonenal (4-HPNE). 4-HPNE can be converted to 4-hydroxy-2E-nonenal by a hydroperoxide-dependent peroxygenase. In the present work we have attempted to purify the

An activity was found in mature soybean seeds (Glycine max L. cv Century) that cleaved 13(S)-hydroperoxy-9(Z),11(E),15(Z)-octadecatrienoic acid (13S-HPOT) into 13-oxo-9(Z),11(E)-tridecadienoic acid and two isomeric pentenols, 2(Z)-penten-1-ol and 1-penten-3-ol. Isomeric pentene dimers were also
