Abstract

Background: PRODH and P5CDH from Thermus thermophilus are monofunctional enzymes in proline catabolism.

Results: Steady-state kinetics and intermediate trapping data show the PRODH and P5CDH reactions are coupled by a channeling step.

Conclusion: Substrate channeling in monofunctional enzymes is achieved via weak interactions.

Significance: Evidence for substrate channeling between monofunctional proline catabolic enzymes is shown and confirms the Rosetta Stone hypothesis.
