==REPLICATION TERMINATOR PROTEIN FROM BACILLUS SUBTILIS==
-
The crystal structure of the replication terminator protein (RTP) of B., subtilis has been determined at 2.6 A resolution. As previously suggested, by both biochemical and biophysical studies, the molecule exists as a, symmetric dimer and is in the alpha + beta protein-folding class. The, protein has several uncommon features, including an antiparallel, coiled-coil, which serves as the dimerization domain, and both an, alpha-helix and a beta-ribbon suitably positioned to interact with the, major and minor grooves of B-DNA. A site has been identified on the, surface of RTP that is biochemically and positionally suitable for, interaction with the replication-specific helicase. Other features of the, structure are consistent with the polar contrahelicase mechanism of the, protein. A model of the interaction between RTP and its cognate DNA is, presented.

== Function ==
 +
[https://www.uniprot.org/uniprot/RTP_BACSU RTP_BACSU] Plays a role in DNA replication and termination (fork arrest mechanism). Two dimers of rtp bind to the two inverted repeat regions (IRI and IRII) present in the termination site. The binding of each dimer is centered on an 8 bp direct repeat.
