The Dicyclohexylcarbodiimide-Binding Protein of Rat Liver Mitochondria as a Product of the Mitochondrial Protein Synthesis

Abstract

A product of mitochondrial protein synthesis in rat liver mitochondria, characterized by a low molecular weight (MW < 10,000) and an unusually high hydrophobicity, was identified as the dicyclohexylcarbodiimide-binding protein and as a peptide of the hydrophobic sector of the mitochondrial ATPase [EC 3.6.1.3] complex. The purified protein still possesses the ability to bind dicylcohexylcarbodiimide.
