text	targets to mitochondria through a N-terminal mitochondrial targeting signal (MTS)

basic FUNCTION	catalyzes the ATP- and NADPH-dependent conversion of L-glutamate to glutamic gamma-semialdehyde, which is the metabolic precursor for proline biosynthesis
	bifunctional enzyme catalyzing the reduction of glutamate to delta 1-pyrroline 5-carboxylate
	acting as a gamma-glutamyl kinase
	acting as a gamma-glutamyl phosphate reductase
	enzyme involved in the de novo synthesis of proline from pyrroline-5-carboxylate (P5C) residing in mitochondria
