    Structural evidence for a common zinc binding domain in archaeal and eukaryal transcription factor IIB proteins

    X-ray absorption spectroscopy has been used to compare the metal coordination of the N-terminal zinc binding domain of eukaryal human transcription factor (TF) IIB to the previously reported structure of arch...

    X-ray absorption spectroscopic analysis of Fe(II) and Cu(II) forms of a herbicide-degrading α-ketoglutarate dioxygenase

     The first step in the degradation of 2,4-dichlorophenoxyacetic acid (2,4-D) by Ralstonia eutropha JMP134 is catalyzed by the α-ketoglutarate (α-KG)-dependent dioxygenase TfdA. Previously, EPR and ESEEM studies o...

    A transcription factor IIB homolog from the hyperthermophilic archaeon Pyrococcus furiosus binds Zn or Fe in an N-terminal Cys4 motif

     The gene for an archaeal homolog of the eukaryotic transcription factor TFIIB has been cloned from the marine hyperthermophilic archaeon Pyrococcus furiosus and overexpressed in Escherichia coli. This TFB gene d...

    Influence of environmental productivity levels and yield stability on selection strategies in soybean

    Yield data were collected for soybean (Glycine max (L.) Merr.) lines in maturity groups III and IV in 14 environments from 1985 to 1989. The lines in each maturity group were subdivided into three different group...
