Abstract

Most popular agents for site-specific protein cleavage are proteolytic enzymes. Because they become denatured and inactivated by detergents, enzymes are inconvenient for proteomic analysis of hydrophobic proteins which require detergents as solubilizing agents. We used cis-[Pd(en)(H(2)O)(2)](2+) (in which en represents ethylenediamine) as an artificial protease to effect cleavage of three bovine proteins, namely ubiquitin, β-casein, and serum albumin, in separate experiments. Cleavage took place in aqueous solutions containing 1.0%wt./vol. of either 3-[(3-Cholamidopropyl)dimethylammonio]-1-propanesulfonate (CHAPS) or Zwittergent 3-14 at 2.5
