General Information

EC Number General Information Comment Organism
2.4.1.85 metabolism UGT85B1 is an important step in product channelling because a rapid glucosylation of the labile p-hydroxymandelonitrile product of CYP71E1 is necessary to avoid its dissociation into p-hydroxybenzaldehyde and hydrogen cyanide Sorghum bicolor
