Degradation pathway for cyclopentanol by Comamonas sp. strain NCIMB 9872 (adapted from reference 27 with permission). CpnA, cyclopentanol dehydrogenase; CpnB, CPMO; CpnC, 5-valerolactone hydrolase; CpnD, 5-hydroxyvalerate dehydrogenase; CpnE, 5-oxovalerate dehydrogenase. An alternative name for 5-valerolactone is 5-pentanolide. Further oxidation of glutarate to acetyl-coenzyme A is believed to proceed via β-oxidation.
