Taxonomic identifier

59922 [NCBI]

Taxonomic lineage

Bacteria › Cyanobacteria › Prochlorophytes › Prochlorococcaceae › Prochlorococcus

Protein attributes

Sequence length	438 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the NADPH dependent reduction of L-gamma-glutamyl 5-phosphate into L-glutamate 5-semialdehyde and phosphate. The product spontaneously undergoes cyclization to form 1-pyrroline-5-carboxylate. HAMAP MF_00412
Catalytic activity	L-glutamate 5-semialdehyde + phosphate + NADP+ = L-glutamyl 5-phosphate + NADPH. HAMAP MF_00412
Pathway	Amino-acid biosynthesis; L-proline biosynthesis; L-glutamate 5-semialdehyde from L-glutamate: step 2/2. HAMAP MF_00412
Subcellular location	Cytoplasm By similarity HAMAP MF_00412.
Sequence similarities	Belongs to the gamma-glutamyl phosphate reductase family.
