CC -!- FUNCTION: Essential for the replication of viral ssDNA. The closed
CC circular ssDNA genome is first converted to a superhelical dsDNA. Rep
CC binds a specific region at the genome origin of replication. It
CC introduces an endonucleolytic nick within the conserved sequence 5'-
CC TAATATTAC-3' in the intergenic region of the genome present in all
CC geminiviruses, thereby initiating the rolling circle replication (RCR).
CC Following cleavage, binds covalently to the 5'-phosphate of DNA as a
CC tyrosyl ester. The cleavage gives rise to a free 3'-OH that serves as a
CC primer for the cellular DNA polymerase. The polymerase synthesizes the
CC (+) strand DNA by rolling circle mechanism. After one round of
CC replication, a Rep-catalyzed nucleotidyl transfer reaction releases a
CC circular single-stranded virus genome, thereby terminating the
CC replication. Displays origin-specific DNA cleavage, nucleotidyl
CC transferase, ATPase and helicase activities.

CC {ECO:0000256|ARBA:ARBA00004123}.
CC -!- DOMAIN: There are 3 rolling circle replication (RCR) motifs. RCR-2 is
CC probably involved in metal coordination. RCR-3 is required for
CC phosphodiester bond cleavage for initiation of RCR.
CC {ECO:0000256|RuleBase:RU361249}.
CC -!- SIMILARITY: Belongs to the geminiviridae Rep protein family.
