4.1.2.10 flavoprotein enzyme shows a typical flavoprotein spectrum with absorption maxima at 389 nm nd 463 nm 4.1.2.10 glycoprotein - 4.1.2.10 glycoprotein molecular mass 97000 Da, mass of deglycosylated protein 62000 Da 4.1.2.10 glycoprotein hydroxynitrile lyase from leaves and that expressed in Pichia pastoris are glycosylated, whereas that expressed in Escherichia coli is not. Predicted mature enzyme has a N-glycosylation site on the asparagine residue at 105 4.1.2.10 glycoprotein the mass difference between the glycosylated and deglycosylated form of the recombinant protein expressed in Aspergillus niger averages to 25 kDa, which indicates that more than one sugar unit is attached to the glycosylated Asn residues
