The solid-state electrical conductivities of a number of ferredoxin model compounds are reported. For one of these compounds, (KFeS(2))(n), an electron transfer rate for a 25 A unit is shown to be at least 1 x 10(8) electrons sec(-1). The rate becomes proportionally larger for smaller molecular units. This rapid rate is consistant with a short pipe model for electron transport between two reaction sites. Some of the factors leading to this rapid transfer rate are considered.
报道了多种铁氧化还原蛋白模型化合物的固态电导率。对于其中一种化合物(KFeS(2))(n)，一个25埃单位的电子转移速率显示至少为1×10(8)个电子/秒。对于更小的分子单位，该速率会相应变大。这种快速速率与两个反应位点之间电子传输的短管道模型相一致。文中考虑了导致这种快速转移速率的一些因素。
