Chemical synthesis and expression of copper metallothionein gene of Neurospora crassa.
The gene coding for the Neurospora crassa copper metallothionein (MT) was synthesized and inserted in the lacZ' gene of pUC18 plasmid to give the same translational reading frame as the latter gene. The MT-beta-galactosidase fused gene was expressed in Escherichia coli to produce a fused protein in which the amino and carboxy termini of MT are linked to the beta-galactosidase through methionine residues. An MT derivative containing an extra homoserine residue at the carboxy terminus was prepared by cyanogen bromide cleavage of the fused protein followed by a reverse-phase HPLC separation. The spectral features of the MT derivative and its copper complex were similar to those of the corresponding native MTs.
