Human tissues contain two enzymes that catalyze the oxidation of the 15-hydroxy group of prostaglandins: NAD-dependent 15-hydroxyprostaglandin dehydrogenase which is fairly specific for prostaglandins and NADP-dependent 15-hydroxyprostaglandin dehydrogenase with low specificity for prostaglandins. The recent determination of the amino acid sequence of the NAD-dependent enzyme has revealed similarities with a number of oxidoreductases with distinct specificities that constitute the short-chain alcohol dehydrogenase family. Comparison of the amino acid sequence of NADP-dependent 15-hydroxyprostaglandin dehydrogenase with the sequences of the NAD-dependent enzyme and other short-chain alcohol dehydrogenases revealed the same similarities, identifying the NADP-dependent enzyme as a short-chain alcohol dehydrogenase. The degree of homology between the two 15-hydroxyprostaglandin dehydrogenases is similar to the one between each of the two enzymes and other members of the family indicating an early evolutionary divergence of the two proteins.

D009249	NADP	Nicotinamide adenine dinucleotide phosphate. A coenzyme composed of ribosylnicotinamide 5'-phosphate (NMN) coupled by pyrophosphate linkage to the 5'-phosphate adenosine 2',5'-bisphosphate. It serves as an electron carrier in a number of reactions, being alternately oxidized (NADP+) and reduced (NADPH).
