Figure 3.

Comparison of overall structure of Pyret with five chromodomain-containing LTR retrotransposons and MoMLV. Boxes indicate ORFs, including putative frames, and vertical lines correspond to stop codons in them. The positions of domains in the gag and pol proteins are indicated. MA, matorix protein; CA, capsid protein; NC, nucleocapsid protein; RT, reverse transcriptase; INT, integrase; CHR, chromodomain; env, envelop protein; MHR, major homology region; ZF, zinc finger motif; W, WCCH motif.
