Protein disulfide isomerase family proteins play important roles in the folding of nascent polypeptides and the formation of disulfide bonds in the endoplasmic reticulum. In this study, we cloned two similar protein disulfide isomerase family genes from soybean leaf (Glycine max L. Merrill. cv

The protein disulfide isomerase is known to play important roles in the folding of nascent polypeptides and in the formation of disulfide bonds in the endoplasmic reticulum (ER). In this study, we cloned a gene of a novel protein disulfide isomerase family from soybean leaf (Glycine max L. Merrill.

β-Conglycinin, one of the major soybean (Glycine max) seed storage proteins, is folded and assembled into trimers in the endoplasmic reticulum and accumulated into protein storage vacuoles. Prior experiments have used soybean β-conglycinin extracted using a reducing buffer containing a sulfhydryl

Protein disulfide isomerase (PDI) and other PDI family proteins are members of the thioredoxin superfamily and are thought to play important roles in disulfide bond formation and isomerization in the endoplasmic reticulum (ER). The exact functions of PDI family proteins in plants remain unknown. In

Multiple enzymatic systems can catalyse protein disulfide bond formation in the endoplasmic reticulum (ER) of eukaryotic cells. The enzyme quiescin sulfhydryl oxidase (QSOX) catalyses disulfide bond formation in unfolded proteins via the reduction of oxygen. We found two QSOX homologues in the

The renaturation of scrambled (oxidized and inactive) RNase A is catalyzed by soybean (Glycine max cv Williams 82) plasma membranes. The catalysis is stimulated by the auxin herbicide 2,4-dichlorophenoxyacetic acid or by the natural auxin indole-3-acetic acid. The inactive auxin analog,

Protein disulfide isomerase (PDI), which catalyses the folding of newly synthesized or denatured proteins through correct disulfide formation, was purified from soybean (Glycine max). The enzyme was purified 12,000-fold over crude extracts to apparent homogeneity in six purification steps: 60-70%

Mitochondria from axes of Glycine max (L.) Merr. cv. Chippewa 64 seedlings purified on discontinuous Percoll gradients exhibited classical cyanide-resistant respiration. These mitochondria also possessed lipoxygenase activity, as determined by O(2) uptake in the presence of 0.8 millimolar linoleic

Protein disulfide isomerase family proteins are known to play important roles in the folding of nascent polypeptides and the formation of disulfide bonds in the endoplasmic reticulum. In this study, we cloned two similar protein disulfide isomerase family genes from soybean leaf (Glycine max L.

Beta-lactoglobulin (beta-Lg) comprises 50% of the whey component of bovine milk. Protein-protein interactions between bovine beta-Lg and 11S protein fractions of soybean and sesame were investigated by turbidity, solubility behaviour and by evaluation of functional properties in the mixed systems.

SBTX, a novel toxin from soybean, was purified by ammonium sulfate fractionation followed by chromatographic steps DEAE-Cellulose, CM-Sepharose and Superdex 200 HR fast-protein liquid chromatography (FPLC). Lethality of SBTX to mice (LD(50) 5.6 mg/kg) was used as parameter in the purification steps.

The thermal denaturation behaviour of glycinin solutions has been studied in situ as a function of ionic strength using various spectroscopic methods. Changes in secondary structure occurred at temperatures above 60 degrees C, well before the onset of gelation. Even after heating to 95 degrees C,

Plant protein tyrosine phosphatases (PTPs) are important in regulating cellular responses to redox change through their reversible inactivation under oxidative conditions. Studies on the soybean (Glycine max) GmPTP have shown that, compared with its mammalian counterparts, the plant enzyme is

Ferric leghemoglobin reductase (FLbR), an enzyme reducing ferric leghemoglobin (Lb) to ferrous Lb, was purified from cowpea (Vigna unguiculata) root nodules by sequential chromatography on hydroxylapatite followed by Mono-Q HR5/5 FPLC and Sephacryl S-200 gel filtration. The purified cowpea FLbR had

Poly(A)-rich RNA was isolated from developing soybean seeds (Glycine max (L.) Merr.) and fractionated on linear log sucrose gradients. Two major fractions sedimenting at 18 S and 20 S were separated and then purified by further sucrose gradient fractionation. Both fractions were active as messengers
