IUBMB Comments
palmitoyl-CoA:sphingoid base N-palmitoyltransferase
Mammals have six ceramide synthases that exhibit relatively strict specificity regarding the chain-length of their acyl-CoA substrates. Ceramide synthase 5 (CERS5) is specific for palmitoyl-CoA as the acyl donor. It can use multiple sphingoid bases including sphinganine, sphingosine, and phytosphingosine.
