show Brenda entry

EC number

1.14.99.32

Accepted name

myristoyl-CoA 11-(Z) desaturase

Reaction

myristoyl-CoA + NAD(P)H + H⁺ + O₂ = (Z)-tetradec-11-enoyl-CoA + NAD(P)⁺ + 2 H₂O

Other name(s)

n-tetradecanoyl-CoA,NADPH:O₂ oxidoreductase [11-(Z) desaturating]

Systematic name

n-tetradecanoyl-CoA,NAD(P)H:O₂ oxidoreductase [11-(Z) desaturating]

CAS registry number

199543-16-3

Comment

Involved in sex pheromone synthesis in the moth Spodoptera littoralis. (Z)-11-Tetradecenoyl-CoA is formed by stereospecific removal of H from the pro-R positions at C-11 and C-12. EC 1.14.99.31, myristoyl-CoA 11-(E) desaturase, forms the (E)-isomer by removing the pro-R H group at C-11 and the pro-S H group at C-12.
