Analysis of Phospholipid-Hydroperoxide Glutathione Peroxidase (PHGPx) protein family. Multiple sequence alignment (CLUSTALX) of protein sequences identified in a cDNA library of unfed/2 d fed or 6 d fed Dermacentor. variabilis midguts (DvM) and Rhipicephalus (Boophilus) microplus (Bm) PHGPx found on genbank. Arrowhead indicates the position of the selenocysteine (X) and the diamond (â—†) indicates the active-site residues Gln and Trp that interact with the selenocysteine. Shading represents 100% identity (black) or similarity (grey) among the sequences. Alignments were conducted using CLUSTALX.
