A27 protein encoding sequence
A24 protein from the Vaccinia virus
Usage and Biology
A27 is a 110 amino acids protein, that consist of the heparin-binding domain, a coiled-coil domain, and the A17 binding leucine zipper domain. The heparin-binding domain contains 21-34 amino acids and has the core sequence KKPE, which is 26-29 amino acids. KKPE is essential for heparin sulfate attachment. Coiled-coil domain, 43-84 amino acids, contributes to self-oligomerization in vitro. Two cysteines at 71 and 72 create a disulfide bond for the self-assembly of A27 and interact with A26. The crystal structure of A27 is a trimeric assembly, consisting of three α-helices, two parallel and one antiparallel. Trimerization can be observed in the N-terminal section. Interaction between trimers occurs at the C-terminal region
