The protein Cdc13p binds telomeresin vivoand is essential for the maintenance of the telomeres ofSaccharomyces cerevisiae. In addition, Cdc13p is known to bind single-stranded TG1–3DNAin vitro. Here we have shown that Cdc13p also binds DNA quadruplex, G-quartet, formed by TG1–3DNA. Moreover, the binding of Cdc13p causes a partial denaturing of the G-quartet DNA. Formation of DNA quadruplexes may involve the intermolecular association of TG1–3DNA and inhibit the extension of telomeres by telomerase. Thus, our finding suggests that Cdc13p may disrupt telomere association and facilitate telomere replication.

In the crystalline state, the low-melting title compound [common name: diphenyltin(IV) dibromide], [SnBr2(C6H5)2], consists of distorted tetrahedral molecules with compressed halide and enlarged carbon opening angles of 102.741 (9) and 123.53 (8)°, respectively, and Sn—C and Sn—Br bond lengths of 2.109 (2)/2.113 (2) and 2.4710 (3)/2.4947 (3) Å, respectively. Intermolecular Sn...Br interactions, typical for diorganotin(IV) dihalides,R2SnHal2(with Hal = Cl, Br, I), and sterically less demanding organic groups lead to the formation of a hitherto unknown association pattern consisting of centrosymmetric dimers with an antiparallel orientation of the dipole moments and two weak intermolecular Sn...Br distances of 3.8482 (3) Å between one of the two Br atoms and its neighbouring Sn atom, andvice versa. The second Br atom is not involved in intermolecular interactions and lies somewhat outside the association plane that, therefore, is not coplanar [interplanar angle = 1.750 (2)°] with the tin–halide plane. The new structure motif of intermolecular tin–halide interaction can be classified as 2ai, which indicates the number of molecules (i.e.`2') composing the oligomer, the antiparallel orientation (i.e.`a') of their dipole moments and the centre of symmetry (i.e.`i') giving rise to the association pattern.
