متن کاملThe unienzymatic nature of yeast polygalacturonase.
Yeast polygalacturonase (YPG) catalyzes the hydrolysis of pectic acid to a mixture of digalacturonic and galacturonic acids (1). The reaction course consists of (a) an initial rapid attack on the linear chain by a random mechanism until about 25 per cent hydrolysis has occurred, (b) a slower phase during which an additional 25 per cent of the available bonds are broken, and (c) an extremely slo...
متن کاملHydrolysis of the oligogalacturonides and pectic acid by yeast polygalacturonase.
Yeast polygalacturonase (YPG) is a constitutive type enzyme, produced exocellularly and free of pectinesterase by Saccharomyces jragilis (1). It has an optimal pH of 4.4 and appears to be specific in its activity towards polygalacturonides (2). YPG differs from preparations of commercial fungus polygalacturonase in that it cannot carry out a complete breakdown of pectic acid to galacturonic aci...
متن کاملRNA Silencing Is Resistant to Low-Temperature in Grapevine
RNA silencing is a natural defence mechanism against viruses in plants, and transgenes expressing viral RNA-derived sequences were previously shown to confer silencing-based enhanced resistance against the cognate virus in several species. However, RNA silencing was shown to dysfunction at low temperatures in several species, questioning the relevance of this strategy in perennial plants such a...
