Delta 1-pyrroline-5-carboxylate reductase signature





Description

Delta 1-pyrroline-5-carboxylate reductase (P5CR) (EC 1.5.1.2) [1,2] is the enzyme that catalyzes the terminal step in the biosynthesis of proline from glutamate, the NAD(P) dependent oxidation of 1-pyrroline-5-carboxylate into proline.

The sequences of P5CR from eubacteria (gene proC), archaebacteria and eukaryotes show only a moderate level of overall similarity. As a signature pattern, we selected the best conserved region located in the C-terminal section of P5CR.
