An example of highlighted residues in an alternative predicted site. The biological unit structure for 2af4 (phosphotransacetylase) is a homodimer and identical active sites are present on both chains. SitesIdentify identifies only one site (in red), but the annotation is transformed onto the other chain in order to identify the other active site (shown in purple).
