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:ARBA00024923, ECO:0000256|RuleBase:RU361249}.

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. CC {ECO:0000256|ARBA:ARBA00006240, ECO:0000256|RuleBase:RU361249}.
