Multiple sequence alignments of evolutionarily related proteins are finding increasing use as indicators of critical amino acid residues necessary for structural stability or involved in functional domains responsible for catalytic activities. In the past, a number of alignments have provided such information for the herpesviral thymidine kinases, for which three-dimensional structures are not yet available. We have sequenced the thymidine kinase gene of a canine herpesvirus, and with a multiple alignment have identified amino acids preferentially conserved in either of two taxons, the genera Varicellovirus and Simplexvirus, of the subfamily Alphaherpesvirinae. Since some regions of the thymidine kinases show otherwise elevated levels of substitutional tolerance, these conserved amino acids are candidates for critical residues which have become fixed through selection during the evolutionary divergence of these enzymes. Several pairs with distinctive patterns of distribution among the various viruses occur in or near highly conserved sequence motifs previously proposed to form the catalytic site, and we speculate that they may represent interacting, co-ordinately variable residues.
