TLDR
The presence of lipoxygenase enzyme is observed when cells oflorella pyrenoidosa are homogenized under anaerobic conditions, the first report of this enzyme in a lower form of plant life.Abstract:
The presence of lipoxygenase enzyme is observed when cells ofChlorella pyrenoidosa are homogenized under anaerobic conditions. This is the first report of this enzyme in a lower form of plant life. The major product ofChlorella lipoxygenase with linoleic acid as substrate is 13-hydroperoxyoctadecadienoic acid.read more

Identification of a Specific Isoform of Tomato Lipoxygenase (TomloxC) Involved in the Generation of Fatty Acid-Derived Flavor Compounds
TL;DR: Together, results suggest that TomloxC is a chloroplast-targeted lipoxygenase isoform that can use both linoleic and linolenic acids as substrates to generate volatile C6 flavor compounds.

Oxidative Systems for Modification of Fatty Acids: The Lipoxygenase Pathway
Brady A. Vick,Don C. Zimmerman +1 more
TL;DR: This chapter discusses the advances in plant lipoxygenase and concludes that a unique physiological role for LOX probably does not exist in plants and it likely has a more general function of responding to plant requirements by synthesizing fatty acid hydroperoxide, the central intermediate for a variety of diverging metabolic pathways.

An anaerobic reaction between lipoxygenase, linoleic acid and its hydroperoxides
TL;DR: It is proposed that the 13-peroxyoctadeca-cis-9-trans-11-dienoic acidradical formed through hydrogen radical abstraction by the linoleic acid radical is the key intermediate for these reactions.

Hydroperoxide Isomerase: A New Enzyme of Lipid Metabolism
Don C. Zimmerman,Brady A. Vick +1 more
TL;DR: The identification of the hydroperoxide isomerase enzyme clarifies the role of lipoxidase in plant tissue and suggests a participation of lipid in the electron transport system.
Journal ArticleDOI
Linoleic acid and trilinolein as substrates for soybean lipoxidase (s).
TL;DR: Evidence has been presented that each of the fractions contains a different type of fat-peroxidizing enzyme, and experimental results indicate that lipoxidases may occur as two groups, i.e., those active on triglycerides and thoseactive on fatty acids.

Specificity of flaxseed lipoxidase
D. C. Zimmerman,B. A. Vick +1 more
TL;DR: Mass spectrometric data indicate that flaxseed lipoxidase possesses a high degree of specificity for attachment of oxygen to linoleic and linolenic acid molecules.
