lipoxygenase/glycine max

Three lipoxygenase isoforms were isolated from Glycine max embryo axes. A number of proteins around 97 kDa cross-reacted with several anti-actin and anti-myosin antibodies and these were used to follow their purification through gel filtration, hydroxyapatite and anion exchange columns. The 97-kDa

The levels of individual lipoxygenase isozymes in soybean [Glycine max (L.) Merr.] leaves were assessed during leaf development, after mechanical wounding, and in response to reproductive sink removal. Native isoelectric focusing followed by immunoblotting was employed to examine individual

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

The consumption of soybean is limited worldwide, despite being highly nutritious and having versatile uses due to the presence of grassy, beany and rancid off-flavour. The lipoxygenase-2 (LOX-2) is the key enzyme responsible for the production of volatiles released from the beans, which cause

BACKGROUND Soybean lipoxygenases (Lxs) play important roles in plant resistance and in conferring the distinct bean flavor. Lxs comprise a multi-gene family that includes GmLx1, GmLx2 and GmLx3, and many of these genes have been characterized. We were interested in investigating the relationship

This study investigated pulsed ultraviolet (PUV) illumination at different distances from the PUV source on soybean lipoxygenase (LOX) (0.4 mg/mL in 0.01 M Tris-HCl buffer, pH 9) activity. Samples (5 mL) were illuminated for 1, 2, 4, 8, and 16 s at 3 distances 6, 8.5, and 11 cm from the PUV lamp's

Natural polyamines are shown to inhibit dioxygenase activity of soybean lipoxygenase-1, but they were ineffective toward the lipoxygenase-2 isozyme. The inhibitory power was dependent on the number of basic groups in the molecule, in the order spermine > spermidine > cadaverine >/= putrescine. Both

Linolenic acid and seed lipoxygenases are associated with off flavours in soybean products. F5 recombinant inbred lines (RILs) from a cross between a low linolenic acid line (RG10) and a seed lipoxygenase-free line (OX948) were genotyped for simple sequence repeats (SSR), random amplified

The genome of pea (Pisum sativum) contains genes encoding a family of distinct lipoxygenases (LOX). Among these, LOXN2 showed eight exons encoding a 93.7-kD enzyme, harboring two C-terminal deletions and an unusual arginine/threonine-tyrosine motif in the domain considered to control the substrate

Several unsaturated aldehydes are produced from polyunsaturated fatty acids via the lipoxygenase pathway when soybean (Glycine max) plants are wounded mechanically or by pathogens. The effects of four of these aldehydes were examined on the growth of isolated fungal cultures ofColletotrichum

Syncytial cells in soybean (Glycine max cultivar [cv.] Peking) roots infected by incompatible and compatible populations of soybean cyst nematode (SCN [Heterodera glycines]) were collected using laser capture microdissection (LCM). Gene transcript abundance was assayed using Affymetrix soybean

Legume crops present important agronomical and environmental advantages mainly due to their capacity to reduce atmospheric N2 to ammonium via symbiotic nitrogen fixation (SNF). This process is very sensitive to abiotic stresses such as drought, but the mechanism underlying this response is not fully

Cloning and sequencing of two cDNAs from mRNA of maturing pea (Pisum sativum) seeds allowed the deduction of the complete amino acid sequence of a lipoxygenase polypeptide which is most similar to that of soya-bean lipoxygenase 2. The predicted Mr of this polypeptide is 97134, and its sequence

A lipoxygenase cDNA clone, pCD45, was identified in a Pisum sativum L. (pea) seed mRNA cDNA library by hybrid-release/translation followed by immunoprecipitation with antiserum raised against lipoxygenase from Glycine max L. (soya bean). pCD45 hybrid-selected an mRNA encoding the larger of the two

The plant parasitic nematode, Heterodera glycines is the major pathogen of Glycine max (soybean). H. glycines accomplish parasitism by creating a nurse cell known as the syncytium from which it feeds. The syncytium undergoes two developmental phases. The first is a parasitism phase where feeding
