Nucleotides and amino acid sequences comparison between MMTV and MPMV. (A) Comparison between MMTV and MPMV cis-acting sequences needed for successful reverse transcription and integration. PBS, primer binding site; PPT poly purine tract; U3 att, attachment site at 3'LTR; U5 att, attachment site at 5'LTR. The boxed areas represent the canonical TG and CA dinucleotides in the U3 and U5 att sequences. The "-" represents homologous sequences, the differences are represented by the actual nucleotides. (B) Amino acid sequence alignment of MPMV RNaseH and integrase with the corresponding region of MMTV using the sequence alignment program, CLUSTAL W. Identical amino acids are boxed.
