KEGG   ENZYME: 4.2.3.131Help
Entry
EC 4.2.3.131                Enzyme                                 

Name
miltiradiene synthase;
SmMDS;
SmiKSL
Class
Lyases;
Carbon-oxygen lyases;
Acting on phosphates
BRITE hierarchy
Sysname
(+)-copaly-diphosphate diphosphate-lyase (cyclizing, miltiradiene-forming)
Reaction(IUBMB)
(+)-copalyl diphosphate = miltiradiene + diphosphate [RN:R10585]
Reaction(KEGG)
Substrate
(+)-copalyl diphosphate [CPD:C11901]
Product
miltiradiene [CPD:C20711];
diphosphate [CPD:C00013]
Comment
Isolated from the plant Selaginella moellendorffii as a mutifunctional enzyme that also catalyses EC 5.5.1.12, copalyl diphosphate synthase [2]. In the plant Salvia miltiorrhiza the two enzymes are separate entities [1].
