Reaction
dTDP-4-dehydro-6-deoxy-α-D-glucopyranose = dTDP-3,4-didehydro-2,6-dideoxy-α-D-glucose + H2O (overall reaction)
(1a) dTDP-4-dehydro-6-deoxy-α-D-glucopyranose = dTDP-2,6-dideoxy-D-glycero-hex-2-enos-4-ulose + H2O
(1b) dTDP-2,6-dideoxy-D-glycero-hex-2-enos-4-ulose = dTDP-3,4-didehydro-2,6-dideoxy-α-D-glucose (spontaneous)
Systematic Name
dTDP-4-dehydro-6-deoxy-α-D-glucopyranose hydro-lyase (dTDP-2,6-dideoxy-D-glycero-hex-2-enos-4-ulose-forming)
Function
The enzyme participates in the biosynthesis of several deoxysugars, including β-L-4-epi-vancosamine, α-L-megosamine, L- and D-olivose, D-oliose, D-mycarose, forosamine and β-L-digitoxose. In vitro the intermediate can undergo a spontaneous decomposition to maltol.
