Sysname
UDP-alpha-D-glucose:N-hydroxy-2-phenylethanethioamide S-beta-D-glucosyltransferase
Reaction(IUBMB)
(1) UDP-alpha-D-glucose + (Z)-2-phenyl-1-thioacetohydroximate = UDP + desulfoglucotropeolin [RN:
R03213 ];
(2) UDP-alpha-D-glucose + an (E)-omega-(methylsulfanyl)alkyl-thiohydroximate = UDP + an aliphatic desulfoglucosinolate [RN:
R12045 ];
(3) UDP-alpha-D-glucose + (E)-2-(1H-indol-3-yl)-1-thioacetohydroximate = UDP + desulfoglucobrassicin [RN:
R08164 ]
Reaction(KEGG)
Substrate
UDP-alpha-D-glucose [CPD:
C00029 ];
(Z)-2-phenyl-1-thioacetohydroximate [CPD:
C03719 ];
(E)-omega-(methylsulfanyl)alkyl-thiohydroximate [CPD:
C21871 ];
(E)-2-(1H-indol-3-yl)-1-thioacetohydroximate [CPD:
C16516 ]
Product
UDP [CPD:
C00015 ];
desulfoglucotropeolin [CPD:
C01069 ];
aliphatic desulfoglucosinolate [CPD:
C21872 ];
desulfoglucobrassicin [CPD:
