A dicotyledon-specific glutaredoxin GRXC1 family with dimer-dependent redox regulation is functionally redundant with GRXC2.

Abstract excerpt

The major known function of glutaredoxins (Grxs) is to reduce disulphide bridges. Recently, some have also been shown to interact with iron-sulphur clusters. These can be classified in two subgroups: class II Grx are found in all living organisms and are implicated in assembly of iron-sulphur clusters, while class I Grx are represented by only two members known to form a holodimer structure containing a cluster...
