Evaluation of cysteine blocking and Zn release effect on E7 conformation and oligomerization state.

<p>(A) Analysis of zinc release from the high affinity coordination center of E7 followed at 500 nm by the formation of Zn(PAR)₂ complex (black circles). The addition of PMPS and DTT is indicated by arrows. Inset, size distribution profile of E7-PMPS measured by DLS. (B) CD spectrum of E7 (black line) and CD spectrum of E7 upon addition of PMPS (dashed line).
