The engineering, structure, and DNA binding properties of a novel His4-type zinc finger peptide.
We have created a novel His4-type zinc finger protein (H4Sp1) engineered by Cys-->His mutations of the Cys2His2-type zinc finger in transcription factor Sp1. The CD and NMR studies reveal that the His4 domain has Zn(II)-dependent folding properties and similar secondary structures to wild-type Cys2His2 domain. The DNA binding experiments demonstrate that H4Sp1 can bind DNA in a specific way. The present artificial peptide H4Sp1 will provide valuable information about the interaction between a metallopeptide and DNA.
