Sysname
1-acyl-2-palmitoyl-[glycerolipid],ferredoxin:oxygen oxidoreductase (9,10 cis-dehydrogenating)
Reaction(IUBMB)
a 1-acyl-2-palmitoyl-[glycerolipid] + 2 reduced ferredoxin [iron-sulfur] cluster + O2 + 2 H+ = a 1-acyl-2-palmitoleoyl-[glycerolipid] + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H2O
Substrate
1-acyl-2-palmitoyl-[glycerolipid];
reduced ferredoxin [iron-sulfur] cluster [CPD:
C00138 ];
O2 [CPD:
C00007 ];
H+ [CPD:
C00080 ]
Product
1-acyl-2-palmitoleoyl-[glycerolipid];
oxidized ferredoxin [iron-sulfur] cluster [CPD:
C00139 ];
H2O [CPD:
C00001 ]
Comment
The enzyme, characterized from the cyanobacterium Nostoc sp. 36, introduces a cis double bond at carbon 9 of palmitoyl groups (16:0) attached to the sn-2 position of glycerolipids.
