Lee et al. BMC Genomics 2011, 12:197 http://www.biomedcentral.com/1471-2164/12/197 Page 4 of 6 Figure 2 Amino acid alignment of predicted translation products of homologous genes from the Serva ILTV strain, the concatenated ILTV reference sequence and other alphaherpesviruses. (A) UL29 gene product. (B) C terminal part of the UL36 gene product. Black boxes indicate 100% identity, dark grey boxes indicate 80-99% identity and pale grey boxes indicate 60-79% identity. Dashes indicate single amino acid gaps in sequence alignments. Alignments were performed using Clustal W version 2.0. The Blosum62 matrix was used to score sequence alignments.
