Product Name acyl-[acyl-carrier-protein] 6-desaturase
Example Structure Example Structure of acyl-[acyl-carrier-protein] 6-desaturase EC#: 1.14.19.26
Synonyms DELTA6 16:0-ACP desaturase, DELTA6 desaturase, DELTA6 palmitoyl-ACP desaturase, DELTA6-16:0-ACP desaturase, DELTA6-palmitoyl (16:0)-ACP desaturase, DELTA6-sphingolipid desaturase, DES6
EC Number 1.14.19.26
CAS Registry Number
Comments The enzyme, characterized from the endosperm of the plant Thunbergia alata (black-eyed Susan vine), introduces a cis double bond at carbon 6 of several saturated acyl-[acyl-carrier protein]s. It is most active with palmitoyl-[acyl-carrier protein] (16:0), but can also act on myristoyl-[acyl-carrier protein] (14:0) and stearoyl-[acyl-carrier protein] (18:0). The position of the double bond is determined by its distance from the carboxyl end of the fatty acid.
Cofactor
History
Reactions Palmitoyl-[acyl-carrier protein] + 2 reduced ferredoxin [iron-sulfur] cluster + O(2) + 2 H(+) = (6Z)-hexadec-6-enoyl-[acyl-carrier protein] + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H(2)O.
