Protein existence	Evidence at transcript level

General annotation (Comments)

Catalytic activity	ATP + L-glutamate = ADP + L-glutamate 5-phosphate. L-glutamate 5-semialdehyde + phosphate + NADP+ = L-glutamyl 5-phosphate + NADPH.
Enzyme regulation	The short isoform is inhibited by L-ornithine with a Ki of approximately 0.25 mm. The long isoform is insensitive to ornithine inhibition. Thus, the two amino acid insert in the long isoform abolishes feedback inhibition of P5CS activity by L-ornithine. Ref.1
Pathway	Amino-acid biosynthesis; L-proline biosynthesis; L-glutamate 5-semialdehyde from L-glutamate: step 1/2. Amino-acid biosynthesis; L-proline biosynthesis; L-glutamate 5-semialdehyde from L-glutamate: step 2/2.
Subcellular location	Mitochondrion inner membrane.
Sequence similarities	In the N-terminal section; belongs to the glutamate 5-kinase family. In the C-terminal section; belongs to the gamma-glutamyl phosphate reductase family.
