Abstract:
... Serine palmitoyltransferase, which is one of the α-oxamine synthase family enzymes, catalyzes the condensation reaction of L-serine and palmitoyl-CoA to form 3-ketodihydrosphingosine, the first and rate-determining step of the sphingolipid biosynthesis. As with other α-oxamine synthase family enzymes, the catalytic reaction is composed of multiple elementary steps, and the mechanism to control the ...
