b-galactosidase from Coffea arabica: Its role in fruit ripening
Date of Publication
b-galactosidase is an enzyme that works in tandem with other enzymes (e.g. polygalacturonase) in the degradation of the plant cell wall. As the fruit ripens, the activity of this enzyme increases. The paper reports on the purification of b-galactosidase from C. arabica, the ability of the enzyme to degrade pectic polysaccharides and its apparent increase in activity during the ripening of the coffee berry. It suggests that b-galactosidase is implicated in cell wall degradation such as occurs during fruit ripening....
