Elaborate arrays of iron–sulfur clusters link active sites via a flavin that bifurcates electrons through two energetically independent paths. The structure of the heterodisulfide reductase provides insight into how methanogens conserve energy through coupling hydrogen oxidation to coordinated exergonic heterodisulfide and endergonic ferredoxin reduction in an overall thermodynamically favorable reaction.

电子分叉使拼图块在产甲烷的能量保护中大幅度落入原位

精心制作的铁硫簇阵列通过黄素链接活性位，黄素通过两条能量独立的路径将电子分叉。杂二硫键还原酶的结构提供了深入的信息，可了解甲烷菌如何通过将氢氧化与配位的能工性异二硫键和二十碳五氧化还原铁还原反应耦合在一起来节省能量，这在总体上对热力学有利。
