Plugging in molecular wires
Date:2/12/2009

removed the vitamin K1 from the PSI protein complex and replaced it with a synthetic analogue. This consists of three parts: 1) The same molecular "plug" with which vitamin K1 is bound to the protein complex (napthoquinone group) is used to "plug in" the synthetic binding component to PSI; 2) a molecular "wire" (hydrocarbon chain) with the same length as in vitamin K1 ensures that the binding component protrudes from the protein complex; and 3) at the other end of the wire is an additional "plug" (viologen group) that anchors the ensemble to a specially coated gold electrode. Electrons released by irradiation of PSI and transmitted along the wire are very efficiently transmitted to the gold electrode by the viologen group.

It may be possible to use this new strategy to integrate other biocomponents into synthetic systems.
