Fig. 5: Reduced LSU-1 and mt-5S rRNAs.

a LSU-1 fragment (pink) is bound by three HEAT protein superimposed with E. coli rRNA (white, PDBID: 7K00). A secondary structure diagram is shown on the right, and protein binding regions are indicated. b The mt-5S rRNA compared with E. coli 5S and their bound proteins. A secondary structure diagram is shown in the middle, and protein binding regions are indicated. c View from the interface of the mammalian mt-LSU of P. magna, H. sapiens (PDBID: 6ZM5) and E. coli shows the arrangement of the 5S rRNA in comparison to the structural CP tRNA. The mitochondria-specific protein mL40 is found regardless of the identity of rRNA in that region.
