Protein
Delta(1)-pyrroline-2-carboxylate reductase
Organism
Bacillus cereus (strain ATCC 14579 / DSM 31 / JCM 2152 / NBRC 15305 / NCIMB 9373 / NRRL B-3711)
Function
Catalyzes the reduction of Delta(1)-pyrroline-2-carboxylate (Pyr2C) to L-proline, using preferentially NADPH over NADH as the electron donor. Is likely involved in a degradation pathway that converts trans-3-hydroxy-L-proline (t3LHyp) to L-proline, which allows B.cereus to grow on t3LHyp as a sole carbon source.
Similarity
Belongs to the ornithine cyclodeaminase/mu-crystallin family.
