“…In some cases, these enzymes present advantages over animal and microbial lipases due to some quite interesting features such as specificity, low cost, availability and ease of purification, representing a great alternative for potential commercial exploitation as industrial enzymes (Polizeli et al, 2008;Parques and Macedo, 2006;Enujagha et al, 2004;Villeneuve, 2003;Hellyer, et al 1999).…”

“…In the mobilization of these three major nutrient reserves during germination, they are hydrolyzed specifically by proteases, amylases and lipases, respectively. Many researchers have investigated seed lipase at the height of its activity during grain germination (Hellyer et al, 1999;Parques and Macedo, 2006). From 20% to 50% of the dry weight of oilseeds is basically stored triacylglycerols.…”

“…According to Hellyer et al (1999), seed lipases show selectivity for the dominant fatty acids in the seed. For example, castor bean lipases show selectivity for triricinolein; palm tree lipase for tricaproin or trilaurein; elm lipase for tricaproin and Vermonia sp.…”

“…Table 1 shows that the seed lipases evaluated had greater activity for the triacylglycerols containing the fatty acids found in higher percentages in the nutrient reserve tissue of that seed. Such affinity is of great physiological significance for the seed (Quettier and Eastmond, 2009;Hellyer et al, 1999;Hammer and Murphy, 1993).…”

-This paper provides an overview regarding the main aspects of seed lipases, such as the reactions catalyzed, physiological functions, specificities, sources and applications. Lipases are ubiquitous in nature and are produced by several plants, animals and microorganisms. These enzymes exhibit several very interesting features, such as low cost and easy purification, which make their commercial exploitation as industrial enzymes a potentially attractive alternative. The applications of lipases in food, detergents, oils and fats, medicines and fine chemistry, effluent treatment, biodiesel production and in the cellulose pulp industry, as well as the main sources of oilseed and cereal seed lipases, are reviewed.

“…More than 200 species have been reported and classified according to the arrangement of double bonds, triple bonds and other modifications [45]. Where a single molecular class of TAG predominates in the seed it appears that selective pressure has yielded a lipase with the appropriate specificity to hydrolyse that TAG following germination [46]. Among the most extreme examples of this typoselectivity appear to be the lipases from ironweed and Cuphea procumbans, which have been reported to exhibit more than 20-fold selectivity for trivernolin and tricaprin, respectively [23,46].…”

Storage oil breakdown plays an important role in the life cycle of many plants by providing the carbon skeletons that support seedling growth immediately following germination. This metabolic process is initiated by lipases (EC: 3.1.1.3), which catalyse the hydrolysis of triacylglycerols (TAGs) to release free fatty acids and glycerol. A number of lipases have been purified to near homogeneity from seed tissues and analysed for their in vitro activities.Furthermore, several genes encoding lipases have been cloned and characterized from plants.However, only recently has data been presented to establish the molecular identity of a lipase that has been shown to be required for TAG breakdown in seeds. In this review we briefly outline the processes of TAG synthesis and breakdown. We then discuss some of the biochemical literature on seed lipases and describe the cloning and characterization of a lipase called SUGAR-DEPENDENT1, which is required for TAG breakdown in Arabidopsis thaliana seeds. presented to establish the molecular identity of a lipase that has been shown to be required for TAG breakdown in seeds.
