The short eALAS is located in the mitochondrial membrane.
Blood (4 mL) was separated on a Ficoll-Hypaque gradient. The high-density fraction was collected and labeled with 22.2 MBq (600 μCi) 35S-methionine for 3 hours. Suborganelles were prepared, and the lysates were used for immunoprecipitation of the eALAS protein followed by gel separation. Lysates of membrane and matrix fractions contained 270 μg protein each.
