| Comment |
Although UDP is generally considered to be the preferred nucleoside
diphosphate for sucrose synthase, numerous studies have shown that
ADP serves as an effective acceptor molecule to produce ADP-glucose
[3-9]. Sucrose synthase has a dual role in producing both
UDP-glucose (necessary for cell wall and glycoprotein biosynthesis)
and ADP-glucose (necessary for starch biosynthesis) [10]. |
