Function
SPEE_THEMA Catalyzes the irreversible transfer of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4-diaminobutane) to yield spermidine. It has lower affinity and lower activity towards 1,3-diaminopropane, cadaverine (1,5-diaminopentane), agmatine, thermine and spermidine (in vitro).[1] [2]
