Protein: L-carnitine dehydrogenase (CDH) (L-CDH) (EC 1.1.1.108) (Q9HTH8)
Organism: Pseudomonas aeruginosa (strain ATCC 15692 / DSM 22644 / CIP 104116 / JCM 14847 / LMG 12228 / 1C / PRS 101 / PAO1)
Function: Catalyzes the NAD(+)-dependent oxidation of L-carnitine to 3-dehydrocarnitine. Is specific for L-carnitine and NAD(+) as substrates. D,L-3-hydroxybutyrate, L-lactate, ethanol, L-malate and D,L-isocitrate are not substrates. Is involved in a L-carnitine degradation pathway that allows P.aeruginosa to grow on L-carnitine as the sole source of carbon and nitrogen.
Subcellular location: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_02129}.
