Pectinlyase
WebPectate lyase (EC 4.2.2.2) catalyzes the cleavage of α-1,4-glycosidic bonds of pectin polymers, and it has potential uses in the textile industry. In this study, a novel pectate lyase belonging to polysaccharide lyase family 10 was screened from the secreted enzyme extract of Paenibacillus polymyxa KF-1 and identified by liquid chromatography-MS/MS. The gene … WebAug 1, 2000 · In pectin lyase, the positive charge is conferred by Arg-176, a conserved arginine in the pectin lyase subfamily. In pectate lyases, the positive charge is conferred by a Ca 2+ ion, which is essential for catalytic activity within the pectate lyase subfamily. The high degree of conservation of the positive charge at analogous positions in the ...

WebAug 1, 2024 · Pectin-lyase is believed to work by creating pores or holes in the grape pectin layers. These pores become larger, which allows the leaching out of more juice (must) volumes. The formation of pores also allows the release of larger molecules, such as grape skin tannins, into the fermentation. In order to produce stable colours and polymeric ...
