Features of the Bagy-2 and Rigy-2 retrovirus-like retrotransposons and their predicted ENV products. (A)Bagy-2. (1) Diagram of the element drawn to scale. Between the long terminal repeats (LTRs) are the predicted gagdomain encoding the capsid protein, the pol domain encoding the proteinase (PR), reverse transcriptase (RT), RNaseH (RH), and integrase (IN), and the putative envelope (env) domain. (2) Diagram of the predicted ENV protein showing putative N-glycosylation sites (↓), consensus proteinase cleavage site (¥), leucine zipper (LZ), and transmembrane domain (TM). (3) Probability plot for occurrence of transmembrane domains. (4) Hydrophilicity plot for the predicted ENV protein. (B)Rigy-2. Features of Rigy-2 as for Bagy-2 inA.
