Fig. 7From: Truncated Rep protein of porcine circovirus 2 (PCV2) caused by a naturally occurring mutation reduced virus replication in PK15 cellsPrimary amino acid sequence alignment and three-dimensional mapping of amino acids for the three PCV2 Rep proteins. a Comparison of the sequences of amino acid residues in the Rep proteins among the three PCV2 isolates. (GenBank accession numbers KU317473, KX831483 and KX831476). b The surface structures of PCV2 Rep proteins were generated based on the amino acid sequences, and displayed using PyMOLBack to article page
