KEGG   ENZYME: 1.14.13.237
Entry
EC 1.14.13.237              Enzyme                                 
Name
aliphatic glucosinolate S-oxygenase;
omega-(methylthio)alkylglucosinolate S-oxygenase;
GS-OX1 (gene name);
omega-(methylthio)alkyl-glucosinolate,NADPH:oxygen S-oxidoreductase
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With NADH or NADPH as one donor, and incorporation of one atom of oxygen into the other donor
Sysname
omega-(methylsulfanyl)alkyl-glucosinolate,NADPH:oxygen S-oxidoreductase
Reaction(IUBMB)
an omega-(methylsulfanyl)alkyl-glucosinolate + NADPH + H+ + O2 = an omega-(methylsulfinyl)alkyl-glucosinolate + NADP+ + H2O [RN:R11804]
Reaction(KEGG)
R11804
Substrate
omega-(methylsulfanyl)alkyl-glucosinolate [CPD:C21691];
NADPH [CPD:C00005];
H+ [CPD:C00080];
O2 [CPD:C00007]
Product
omega-(methylsulfinyl)alkyl-glucosinolate [CPD:C21692];
NADP+ [CPD:C00006];
H2O [CPD:C00001]
Comment
The enzyme is a member of the flavin-dependent monooxygenase (FMO) family (cf. EC 1.14.13.8). The plant Arabidopsis thaliana contains five isoforms. GS-OX1 through GS-OX4 are able to catalyse the S-oxygenation independent of chain length, while GS-OX5 is specific for 8-(methylsulfanyl)octyl glucosinolate.
