RT   in the spiroplasmal host chromosome.";
RL   Curr. Microbiol. 32:134-140(1996).
CC   -!- FUNCTION: This protein may encode an integrase, which is necessary for
CC       integration of the viral DNA into host genome.
CC   -!- SIMILARITY: Belongs to the plectrovirus integrase ORF3 family.
CC       {ECO:0000305}.
