}}Thermospermine synthase ({{EC number|2.5.1.79}}, TSPMS, ACL5 (ACAULIS5), SAC51) is an enzyme with systematic name S-adenosylmethioninamine:spermidine 3-aminopropyltransferase (thermospermine synthesizing).[1][2][3] This enzyme catalyses the following chemical reaction
S-adenosylmethioninamine + spermidineS-methyl-5'-thioadenosine + thermospermine + H+
This enzyme is required for correct xylem specification through regulation of the lifetime of the xylem elements.
