The PII proteins constitute a large superfamily, present in all domains of life. Until now, PII proteins research in Chloroplastida (green algae and land plants) has mainly focused on post-translation regulation of these signal transductors.

The crystal structure of theSchizosaccharomyces pombe Holliday junction resolvase Ydc2 revealed significant struc-tural homology with the Escherichia coliresolvase RuvC but Ydc2 contains a small triple helical bundle that has no equivalent in RuvC.Two of thea-helices that form this bundle show homology to a putative DNA-binding motif known as SAP.To investigate the biochemical function of the triple-helix domain, truncated Ydc2 mutants were expressed inE.coliand in fission yeast.

The gene coding for a hemoglobin-like protein (Tf-trHb) has been identi-fied in the thermophilic actinobacteriumThermobifida fuscaand cloned in Escherichia colifor overexpression. The crystal structure of the ferric, ace-tate-bound derivative, was obtained at 2.48 A ˚ resolution. The three-dimen-sional structure of Tf-trHb is similar to structures reported for the truncated hemoglobins from Mycobacterium tuberculosisandBacillus sub-tilis in its central domain.

Cadherins belong to a family of homophilic cell–cell adhesion proteins that are responsible for the establishment of a precise cell architecture and tissue integrity. Moreover, experimental data suggest that loss of intercellular adhesion is inversely correlated with cellular differentiation. Furthermore, dedifferentiation is closely linked to tumor progression.

Campylobacter jejunihosts two hemoglobins (Hbs). TheCamplylobacter je-juni single-domain Hb (called Cgb) is homologous to the globin domain of flavohemoglobin, and it has been proposed to protect the bacterium against nitrosative stress.
