Preparation and application of lacto-N-biose synthases immobilized onto amino-modified SiO2 nanoparticles.
Lacto-N-biose (LNB) is the core structural unit of human milk oligosaccharides and plays an indispensable role in the growth and development of infants. In this study, amino-modified SiO2 nanoparticles (SNPs-NH2) were used as carriers to immobilize sucrose phosphorylase (SPase), UDP-galactose-4'-epimerase (GalE), galac...
