Description/Abstract A cyclic electron transport pathway around photosystem I, involving membrane-bound FNR, is described that is capable of generating both transmembrane electric field and proton gradient.^The major distinctive features of this cycle are that it does not require the presence of soluble ferredoxin or NADPH, it is insensitive to antimycin A, and poising with O/sub 2/ is not necessary for its continuous operation.^Moss and Bendall previously detected an antimycin-insensitive component in cyclic electron flow supported by ferredoxin, and suggested the existence of an alternative cyclic pathway such as that reported here.^Bound ferredoxin that is presumed to be associated with membrane-bound FNR may also take part in this antimycin-insensitive pathway.^13 refs., 4 figs.
