The crystal structure of Sod2 from Saccharomyces cerevisiaeThe crystal structure of Sod2 from Saccharomyces cerevisiae

Structural highlights

3bfr is a 1 chain structure with sequence from Atcc 18824. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Gene:SOD2 (ATCC 18824)
Activity:Superoxide dismutase, with EC number 1.15.1.1
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum

Function

[SODM_YEAST] Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

The manganese-specific superoxide dismutase SOD2 from the yeast Saccharomyces cerevisiae is a protein that resides in the mitochondrion and protects it against attack by superoxide radicals. However, a high iron concentration in the mitochondria results in iron misincorporation at the active site, with subsequent inactivation of SOD2. Here, the crystal structures of SOD2 bound with the native metal manganese and with the `wrong' metal iron are presented at 2.05 and 1.79 A resolution, respectively. Structural comparison of the two structures shows no significant conformational alteration in the overall structure or in the active site upon binding the non-native metal iron. Moreover, residues Asp163 and Lys80 are proposed to potentially be responsible for the metal specificity of the Mn-specific SOD. Additionally, the surface-potential distribution of SOD2 revealed a conserved positively charged electrostatic zone in the proximity of the active site that probably functions in the same way as in Cu/Zn-SODs by facilitating the diffusion of the superoxide anion to the metal ion.
