Figure 2.

Cn3D display of 1AYL's structure and the sequence-structure alignment between 1AYL and the protein product of APE0033. Aligned residues are shown in uppercase in the sequence window, and identical ones are colored in red. Selected functional residues in 1AYL are shown in the structure window, along with substrates and cofactors. It can be seen from the alignment, that the majority of these residues are conserved in 1AYL and APE0033.
