... The unusual methanogenic seryl-tRNA synthetase recognizes tRNA Ser species from all three kingdoms of life Silvija Bilokapic 1,2 , Dragana Korencic 2,3 , ... unpublished data). One of these enzymes is bacteria-like SerRSs, while the other is atypical archaeal SerRS [16], which is only marginally related to the homologues in nonmethanogenic species and outside...

... forms of the MAPKs were produced as GST-lofMPK3 and GST- lofMPK6. However, when lofMPK3 and lofMPK6 proteins were tested for phosphorylation with OXI1, no phosphorylation of lofMPK3 or lofMPK6 ... [17]. On the other hand, expression of the tomato SlPti1 cDNA in the rice Ospti1a mutant suppressed the mutant phenotype. These results indicate that PTI1 acts as a negative reg- ula...

... We focus on the function and relationship of the two single domains. Additionally, the possibility that fusion of the PhyH N-terminal domain to other single-domain BPPs would improve the catalytic ... they can increase the amount of available phosphate by interacting together. Additionally, fusing PhyH-DI to a single-domain phytase appears to be an efficient way to improve t...

... turns of the DNA double helix yields binding of the two or three NF-Y complexes on the same side of the DNA. Conservation of spacing is required for optimal pro- moter activity because changing the ... together with the E2F site [20,21]. The DRS ⁄ CHR in the B-Myb pro- moter deviates most from other CHR sequences with its two-nucleotide exchange from the CHR co...

The key event in the mito- chondrial pathway is the release of proapoptotic fac- tors from the mitochondrial intermembrane space into the cytosol, ... release of cytochrome c and second mitochondria-derived activator of caspase (Smac ⁄ DIABLO) allows for the formation of the apoptosome, a complex that enabl...

... of the presence of ribosomal proteins in the TIAR-TAP pellet is difficult to address because ribosomal proteins are common contaminants of TAP assays [43,44]. On the other hand, the presence of ... tethering of TTP to the same reporter mRNA. These results indicate that ASF ⁄ SF2 is a potent repressing factor in the absence of competing factors. It is worth noting that...

The contribution of these over-metallated species is also apparent in the stoichiometry ... Cd 6 -CeMT-2 and other MTs (Table 2), even when the effect of the over-metallated species is taken into account. To date, the overall stability of cadmium binding to CeMT-1...
