RodZ (also known as YfgA) is a component of the core bacterial morphogenic apparatus. RodZ is a key cell shape determinant in rod-shaped bacteria and it interacts with the actin-like cytoskeletal protein MreB. In Bacillus subtilis, this 304-residue transmembrane protein is composed of three distinct domains: a cytoplasmic domain (RodZn), a transmembrane domain, and an extra-cytoplasmic domain (RodZc). Here we report the (1)H, (13)C and (15)N backbone and side chain resonance assignments of the RodZc domain from B. subtilis by NMR spectroscopy, and the resulting secondary structure prediction.

Lipid-modified azurin (Laz) from Neisseria gonorrhoeae is a type 1 copper protein proposed to be the electron donor to several enzymes involved in the resistance mechanism to reactive oxygen and nitrogen species. Here we report the backbone and side-chain resonance assignment of Laz in the reduced form, which has been complete at 97%. The predicted secondary structure indicates that this protein belongs to the azurin subfamily of type 1 copper proteins.

Enzymes produced by psychrophilic organisms have successfully overcome the low temperature challenge and evolved to maintain high catalytic rates in their permanently cold environments. As an initial step in our attempt to elucidate the cold-adaptation strategies used by these enzymes we report here the (1)H, (15)N and (13)C assignments for the reduced form of a thiol-disulphide oxidoreductase from the Antarctic bacterium Pseudoalteromonas haloplanktis TAC125.
