Zinc metalloregulation of the zinc finger pair domain.


The yeast transcriptional activator Zap1 contains two uncommon structural motifs designated zinc finger pair domains. The hallmark of this domain is the packing of two zinc finger motifs in one globular unit. One finger pair domain in Zap1 contains the AD2 transactivation domain. Zn(II) binding to this domain (ZF1/2) is kinetically labile yielding a zinc… (More)
