Abstract

ATP-citrate lyase has been purified from rat brain by a new procedure which yields an enzyme of specific activity of 21 U/mg protein (37 °C) (2050-fold purification). Purity (by sodium dodecyl sulfate-gel electrophoresis) of the preparation was comparable to that of rat liver ATP-citrate lyase of similar specific activity. Both brain and liver ATP-citrate lyase have the same electrophoretic mobility, as well as the same immunoreactivity against specific rabbit anti-rat liver ATP-citrate lyase antibody. These data indicate that rat brain ATP-citrate lyase is similar or identical to that present in rat liver. Intraperitoneally injected 32Pi was incorporated into the structural phosphate of ATP-citrate lyase in rat liver but not into the rat brain enzyme.
