Characterization of the response to zinc deficiency in the cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2012)
Zur regulators control zinc homeostasis by repressing target genes under zinc-sufficient conditions in a wide variety of bacteria. This paper describes how part of a survey of duplicated genes led to the identification of ...

The cytochrome f–plastocyanin complex as a model to study transient interactions between redox proteins
(Wiley, 2012)
Transient complexes, with a lifetime ranging between microseconds and seconds, are essential forbiochemical reactions requiring a fast turnover. That is the case of the interactions between proteinsengaged in electron ...

The function of the NADPH thioredoxin reductase C-2-Cys peroxiredoxin system in plastid redox regulation and signalling
(Elsevier, 2012)
Protein disulphide–dithiol interchange is a universal mechanism of redox regulation in which thioredoxins (Trxs) play an essential role. In heterotrophic organisms, and non-photosynthetic plant organs, NADPH provides the ...
