Template:STRUCTURE 3a2b Serine palmitoyltransferase (SPT) catalyzes the conversion of palmitoyl-CoA and serine to CoA and dehydro-sphinganine. This reaction is part of sphingosine biosynthesis. Pyridoxal phosphate is a cofactor in the reaction. The prokaryotic SPT is a soluble homodimer while the eukaryotic one is heterodimeric and is anchored in the endoplasmic reticulum.
