Plant thioredoxins and glutaredoxins: identity and putative roles

Thioredoxins and glutaredoxins are ubiquitous proteins that reduce disulphide bridges of oxidized target proteins in vitro. In contrast to the situations in other organisms, phylogenic analysis has indicated that plant thioredoxins and glutaredoxins are present as multigenic families, and that thioredoxins have several subclasses. Thioredoxins and glutaredoxins are probably involved in similar physiological events - the major challenge is to identify their specific targets and establish the function of these proteins in vivo.
