Description
Pectolyase catalyzes the eliminative cleavage of a-(1-4)-Dgalacturonan methyl ester to give oligosaccharides with 4-deoxy-6-O-methyl-a-D-galact-4-enuronosyl groups at their non-reducing ends. It contain two types of pectinase, endopolygalacturonase, endo-pectin lyase and a maceration stimulating factora.
Abbr
PEL1, Native (Aspergillus japonicus)
Source
Aspergillus japonicus
Applications
Used in plant protoplast preparation to digest cell wall prior to organelle isolation. Pectolyase P5936 (Pel1) is a natural mixed pectolyase produced by the fungus Aspergillus japonicus used to digest components (endopolygalacturonate and pectin) of plant cell walls. Treatment of cell walls with pectolyase can be used to destablilize the cell walls for organelle isolation or to modify the elasticity of the cell walls.
