Functioni

Catalyzes the irreversible transfer of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4-diaminobutane) to yield spermidine.UniRule annotation

Catalytic activityi

S-adenosyl 3-(methylthio)propylamine + putrescine = 5'-S-methyl-5'-thioadenosine + spermidine.UniRule annotation

Pathwayi: spermidine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes spermidine from putrescine.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Polyamine aminopropyltransferase (speE)
This subpathway is part of the pathway spermidine biosynthesis, which is itself part of Amine and polyamine biosynthesis.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
