EC 2.5.1.79
Names
Accepted name:
thermospermine synthase
Other
names:
TSPMS
ACL5
SAC51
ACL5
SAC51
Systematic name:
S-adenosyl 3-(methylsulfanyl)propylamine:spermidine 3-aminopropyltransferase (thermospermine synthesizing)
Reaction
- S-adenosyl 3-(methylthio)propylamine + spermidine = S-methyl-5'-thioadenosine + thermospermine + H+
Comments:
This enzyme is required for correct xylem specification through regulation of the lifetime of the xylem elements [3].
