'''Solution structure of the Z-DNA binding domain of the vaccinia virus gene E3L'''<br />


==Overview==
==Solution structure of the Z-DNA binding domain of the vaccinia virus gene E3L==
The N-terminal domain of the vaccinia virus protein E3L (Z alpha(E3L)) is, essential for full viral pathogenicity in mice. It has sequence similarity, to the high-affinity human Z-DNA-binding domains Z alpha(ADAR1) and Z, alpha(DLM1). Here, we report the solution structure of Z alpha(E3L) and, the chemical shift map of its interaction surface with Z-DNA. The global, structure and the Z-DNA interaction surface of Z alpha(E3L) are very, similar to the high-affinity Z-DNA-binding domains Z alpha(ADAR1) and Z, alpha(DLM1). However, the key Z-DNA contacting residue Y48 of Z alpha(E3L), adopts a different side chain conformation in unbound Z alpha(E3L), which, requires rearrangement for binding to Z-DNA. This difference suggests a, molecular basis for the significantly lower in vitro affinity of Z, alpha(E3L) to Z-DNA compared with its homologues.

== Publication Abstract from PubMed ==
The N-terminal domain of the vaccinia virus protein E3L (Z alpha(E3L)) is essential for full viral pathogenicity in mice. It has sequence similarity to the high-affinity human Z-DNA-binding domains Z alpha(ADAR1) and Z alpha(DLM1). Here, we report the solution structure of Z alpha(E3L) and the chemical shift map of its interaction surface with Z-DNA. The global structure and the Z-DNA interaction surface of Z alpha(E3L) are very similar to the high-affinity Z-DNA-binding domains Z alpha(ADAR1) and Z alpha(DLM1). However, the key Z-DNA contacting residue Y48 of Z alpha(E3L) adopts a different side chain conformation in unbound Z alpha(E3L), which requires rearrangement for binding to Z-DNA. This difference suggests a molecular basis for the significantly lower in vitro affinity of Z alpha(E3L) to Z-DNA compared with its homologues.


==About this Structure==
The solution structure of the N-terminal domain of E3L shows a tyrosine conformation that may explain its reduced affinity to Z-DNA in vitro.,Kahmann JD, Wecking DA, Putter V, Lowenhaupt K, Kim YG, Schmieder P, Oschkinat H, Rich A, Schade M Proc Natl Acad Sci U S A. 2004 Mar 2;101(9):2712-7.
