A0A6N7TKP8 · A0A6N7TKP8_9FIRM

Function

function

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

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.
The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

Catalytic activity

Pathway

Amine and polyamine biosynthesis; spermidine biosynthesis; spermidine from putrescine: step 1/1.
