Archaeal translation initiation factor 2 (aIF2) is homologous to its eukaryotic counterpart (eIF2). It is a heterotrimeric protein consisting of α, β, and γ subunits. The protein e/aIF2 forms a ternary complex with guanosine 5′-triphosphate and the initiator methionyl-tRNA (Met-tRNAi) and delivers the latter to the ribosome. In archaea, translation initiation factor 2 has an additional function. The γ subunit of aIF2 binds mRNAs with a triphosphate at the 5′-end and prevents 5′-to-3′ directional mRNA decay. To determine the mRNA-binding site on the surface of aIF2γ, mutations were introduced into the protein sequence at sites of possible interactions with mRNA. The crystals of the mutant forms of aIF2γ were obtained, and X-ray diffraction data sets suitable for structure determination at atomic resolution were collected. 相似文献

Aluminum creep acceleration at applying an electric potential to ±1 V has been established experimentally. The fracture surface
and side surface microrelief near the fracture surface were investigated by scanning electron microscopy. It is shown that
application of ±1 V potential leads to decrease in the fracture toughness. Possible reasons for this phenomenon are considered. 相似文献
