Shah, Sonya C. published the artcileCovalent modification of cytochrome c with a hydrazone complex of platinum(II), COA of Formula: C11H10N4, the publication is Journal of the Serbian Chemical Society (1988), 53(3), 139-48, database is CAplus.
The complex Pt(sbpaphy)Cl– (where sbpaphy is 2-(3-sulfobenzoyl)-pyridine-2-aldehyde 2′-pyridylhydrazone) modifies selectively the histidine (His) 33 residue in horse heart cytochrome c at pH 7.0. The reaction takes place under mild conditions and the Pt(sbpaphy)His label is stable at pH 7.0. The binding site is identified by UV-vis spectrophotometry and by studies of model complexes. The labeled protein is purified readily by cation-exchange chromatog. and the inorganic chromophore in it is quantitated easily owing to its strong UV absorption bands. Cyclic voltammetry, differential-pulse voltammetry, and UV-vis spectrophotometry show that labeling does not perturb the protein.
