Introduction
Biochemistry
- carnitine biosynthesis 1
- enzyme: methyltransferase
- substrate: protein + 3 S-adenosylmethionine
- product: protein with lys[CH3]3) + 3 S-adenosylhomocysteine
- carnitine biosynthesis 2
- enzyme: protease
- substrate: protein with lys[CH3]3 + H2O
- product: peptide proteolyticfragment + trimethyllysine
- carnitine biosynthesis 3
- enzyme: trimethyllysine hydroxylase
