Figure 2. Cα Superposition of the AlkA Azaribose LRC Structure onto an AlkA/DNA Subunit from the AlkA HGC.

Figure 2

The rmsd of the LRC (the protein is colored cyan as in Figure 1B; DNA colored white) onto the HGC subunit (colored as in Figure 1C) is 0.37 Å. The crimson dot denotes the position of the phosphate that hydrogen bonds with the protein backbone at positions 249 and 251 (yellow loop); this phosphate is the only element of the otherwise naked central portion of the DNA that is contacted by the protein. The major sites of protein:DNA interaction are colored as in Figure 1C.
