Accepted name: prostamide/prostaglandin F synthase
Reaction: thioredoxin + (5Z,9α,11α,13E,15S)-9,11-epidioxy-15-hydroxy-prosta-5,13-dienoate = thioredoxin disulfide + (5Z,9α,11α,13E,15S)-9,11,15-trihydroxyprosta-5,13-dienoate
Glossary: prostamide H2 = (5Z)-N-(2-hydroxyethyl)-7-{(1R,4S,5R,6R)-6-[(1E,3S)-3-hydroxyoct-1-en-1-yl]-2,3-dioxabicyclo[2.2.1]hept-5-yl}hept-5-enamide
prostamide F = (5Z,9α,11α,13E,15S)-9,11,15-trihydroxy-N-(2-hydroxyethyl)prosta-5,13-dien-1-amide
prostaglandin H2 = (5Z,9α,11α,13E,15S)-9,11-epidioxy-15-hydroxy-prosta-5,13-dienoate
prostaglandin F = (5Z,9α,11α,13E,15S)-9,11,15-trihydroxyprosta-5,13-dienoate
Other name(s): prostamide/PGF synthase; prostamide F synthase; prostamide/prostaglandin F synthase; tPGF synthase
Systematic name: thioredoxin:(5Z,9α,11α,13E,15S)-9,11-epidioxy-15-hydroxy-prosta-5,13-dienoate oxidoreductase
Comments: The enzyme contains a thioredoxin-type disulfide as a catalytic group. Prostamide H2 and prostaglandin H2 are the best substrates; the latter is converted to prostaglandin F. The enzyme also reduces tert-butyl hydroperoxide, cumene hydroperoxide and H2O2, but not prostaglandin D2 or prostaglandin E2.
