From: An insight into the sialome of Glossina morsitans morsitans
Alignment of the active center region of Culex quinquefasciatus endonuclease with Glossina morsitans morsitans proteins of the same family. The ten amino acids making contact to substrate, based on the Serratia marcescens crystal structure, are shown in turquoise background for the Culex and Glossina sequences. Note the absence of three conserved residues in the tsetse proteins. Other conserved residues are marked in yellow background.
