Secondary and overall tertiary structure of E. coli tRNAAsp. (A) Secondary structure diagram of E. coli tRNAAsp. (B,C) Overall tertiary structure of the two molecules of E. coli tRNAAsp (denoted as A,B) that comprise the crystallographic asymmetric unit. (D) Juxtaposition of the two structures reveal several conformational differences between the two models.
