Purification and partial characterization of a fatty acidbinding protein from the yeast, Yarrowia lipolytica

A low-molecular-mass fatty acid-binding protein was isolated from the cytosol of the yeast Yarrowia lipolytica. Purification was achieved by a two-step procedure involving size-exclusion and cation-exchange chromatography. The isolated protein exists as a monomer of 15 kDa, is basic and has a blocked N-terminus. Internal amino acid sequencing suggests that this protein may belong to a novel class of fatty acid-binding proteins.
