MeSH Heading: Spermidine Synthase
Tree Number(s): D08.811.913.225.825
Unique ID: D011436
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D011436
Annotation: do not confuse with SPERMINE SYNTHASE
Scope Note: An enzyme that catalyzes the transfer of the propylamine moiety from 5'-deoxy-5'-S-(3-methylthiopropylamine)sulfonium adenosine to putrescine in the biosynthesis of spermidine. The enzyme has a molecular weight of approximately 73,000 kDa and is composed of two subunits of equal size.
