Abstract: An allene-acetylene isomerase (AAI) isolated from hog liver interconverts the N- acetylcysteamine thio ester of 3-decynoic acid (3-decynoyl-NAC) and (+)-2, 3-decadienoyl- NAC. It is thus far the only enzyme that has been isolated that produces (or utilizes) an allenic compound and that is not inactivated by that same allene. Although physical and kinetic characteristics of the enzyme have previously been obtained, details of its ...
