Structural comparisons between Maf and selected proteins. (A) Secondary structure of the C-terminal putative anticodon-binding domain of glycyl-tRNA synthetase (Upper) and structural comparison between Maf and glycyl-tRNA synthetase [red and blue, respectively (Lower)]. (B) Secondary structure of E. coli RNase H (Upper) and structural comparison between the N-terminal portion of Maf and the C-terminal portion of RNase H [red and blue, respectively (Lower)]. The β strands 3, 4, and 5 in glycyl-tRNA synthetase and phosphoglucomutase correspond to strands 3, 5, and 6 in Maf (Fig. 1B). Similarly, β strands 1, 2, and 3 in RNase H correspond to strands 3, 5, and 6 in Maf.
