Replication initiation protein, N-terminal
This domain is found at the N-terminal end of Replication initiation protein from Staphylococcus aureus (RepD) and similar bacterial sequences. RepD shows similarity with the extended beta-sheet in TATA binding protein (TBP) [1]. Paper describing PDB structure 4cwc. [1]. 26792891. Structures of replication initiation proteins from staphylococcal antibiotic resistance plasmids reveal protein asymmetry and flexibility are necessary for replication.

replication initiation factor domain-containing protein
Plasmid replication is initiated by the replication initiation factor (REP). This family represents a probable topoisomerase that makes a sequence-specific single-stranded nick in the plasmid DNA at the origin of replication. Human proteins also belong to this family, including myelin transcription factor 2 (Swiss:O15150) and cerebrin-50 (Swiss:Q16301) [2]. [1]. 2270231. Nucleotide sequence of the rep gene of staphylococcal plasmid pCW7. Balson DF, Shaw WV;. Plasmid 1990;24:74-80. [2]. 7735128. Cerebrin-50, a human cerebrospinal fluid protein whose mRNA is present in multiple tissues but predominantly expressed in the lymphoblastoid cells and the brain.
