The crystal structure of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) from the hyperthermophilic archaeonHyperthermus butylicusis presented at 1.8 Å resolution. Previous structures of archaeal Rubisco have been found to assemble into decamers, and this oligomerization was thought to be required for a highly thermally stable enzyme. In the current study,H. butylicusRubisco is shown to exist as a dimer in solution, yet has a thermal denaturation midpoint of 114°C, suggesting that high thermal stability can be achieved without an increased oligomeric state. This increased thermal stability appears to be due to an increased number of electrostatic interactions within the monomeric subunit. As such,H. butylicusRubisco presents a well characterized system in which to investigate the role of assembly and thermal stability in enzyme function.

The paper shows that high thermal stability of the ultrafine-grained structure of aluminum alloy produced by severe plastic deformation is related to S-phase particles. The sequence of phase transformations of zirconium-doped ultrafine-grained alloy Al-Mg-Li in heating is revealed. The paper also determines temperatures at which depending on crystal structure two types of S-phase particles can form.
