	intracellular,nucleus
text	synthesized on the rough endoplasmic reticulum and subsequently transferred across the outer and inner membranes of mitochondria, a process requiring additional processing by peptidases and protection by chaperones for proper folding

basic FUNCTION	catalyzing the first step of porphyrin biosynthesis, pyridoxal dependent
	rate-limiting enzyme in heme synthesis in the liver and is highly regulated to adapt to the metabolic demand of the hepatocyte (
	first rate controlling enzyme that controls cellular heme biosynthesis
