In Vitro Ferredoxin-Dependent Desaturation of Fatty Acids in Cyanobacterial Thylakoid Membranes

J Bacteriol. 1993 Jan;175(2):544-7. doi: 10.1128/jb.175.2.544-547.1993.

Abstract

Thylakoid membranes isolated from the cyanobacterium Synechocystis sp. strain PCC6803 were capable of desaturating the acyl groups in monogalactosyl diacylglycerol. This desaturation reaction required the reduced form of ferredoxin.
