2.A.1.25.1
The endoplasmic reticular/Golgi acetyl-CoA:CoA antiporter 1, ACATN/ACATN1 (SLC33A1).  Allows acetylation of sialic acid residues in gangliosides and lysine residues in membrane proteins.  It is associated with neurodegenerative disorders such as sporadic amyotrophic laterial sclerosis (ALS) and Spastic Paraplegia 42, and it is essential for motor neuron viability (Hirabayashi et al. 2013). Abnormal concentrations of acetylated amino acids in cerebrospinal fluid are observed in acetyl-CoA transporter deficiency (Šikić et al. 2022).
