Fig. 1From: HTLV-1 reverse transcriptase homology model provides structural basis for sensitivity to existing nucleoside/nucleotide reverse transcriptase inhibitorsMMLV, HTLV-1, HIV-1, and HERV-K sequence alignment. Amino acid sequence alignment of MMLV, HTLV-1, HIV-1, and HERV-K. Amino acids conserved between all three viruses are highlighted in red with white text. For those residues considered for at least two viruses are outlined in blue with red text. Insertions are represented by a periodBack to article page
