Application

p-Nitrophenyl galacto-N-bioside has been used as a substrate to assay the activity of α-galactosidase (AnGAL), rhamnogalacturonan acetylesterase (AnRAE), and α-L-arabinofuranosidasae (AnAF). It has also been used as a disaccharide model substrate to assay endo-GalNAc-ase S activity in the culture broths.

Biochem/physiol Actions

Substrate for O-glycosidase.

Agrobacterium-mediated transformation is widely used to produce insertions into plant genomes. There are a number of well-developed Agrobacterium-mediated transformation methods for dicotyledonous plants, but there are few for monocotyledonous plants. Three hydrolase genes were transiently expressed in Brachypodium distachyon plants
