show Brenda entryEC number
1.14.19.78
Accepted name
decanoyl-[acyl-carrier protein] acetylenase
Reaction
decanoyl-[acyl-carrier protein] + 4 reduced ferredoxin [iron-sulfur] cluster + 2 O2 + 4 H+ = dec-9-ynoyl-[acyl-carrier protein] + 4 oxidized ferredoxin [iron-sulfur] cluster + 4 H2O (overall reaction);;(1a) decanoyl-[acyl-carrier protein] + 2 reduced ferredoxin [iron-sulfur] cluster + O2 + 2 H+ = dec-9-enoyl-[acyl-carrier protein] + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H2O;;(1b) dec-9-enoyl-[acyl-carrier protein] + 2 reduced ferredoxin [iron-sulfur] cluster + O2 + 2 H+ = dec-9-ynoyl-[acyl-carrier protein] + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H2O
Other name(s)
ttuB (gene name) (ambiguous)
Systematic name
decanoyl-[acyl-carrier protein],reduced ferredoxin:oxygen oxidoreductase (9,10-dehydrogenating)
Comment
The enzyme, characterized from the bacterium Teredinibacter turnerae, is specific for decanoyl-[acyl-carrier protein]. Activity is maximal when decanoate is loaded onto a dedicated acyl-carrier protein (TtuC), which is encoded by a gene in the same operon.
