Organism
Streptococcus pyogenes serotype M49 (strain NZ131)
Function
Catalyzes the hydration of oleate at its cis-9-double bond to yield 10-hydroxyoctadecanoate, and of linoleate at its cis-9- and cis-12-double bond to yield 10-hydroxy-12-octadecenoate and 10,13-dihydroxyoctadecanoate. Is not active on trans-double bonds and esterified fatty acids as substrate; is only active on cis-9- and/or cis-12-double bond of C16 and C18 fatty acids without any trans-configurations, producing 10-hydroxy and 10,13-dihydroxy derivatives. Appears to play a role in oleic acid detoxification and bacterial virulence.
Similarity
Belongs to the oleate hydratase family.
