CAS Registry Number
Comments
The apolipoprotein B mRNA editing enzyme complex catalyses the editing of apolipoprotein B mRNA at cytidine6666?to uridine, thereby transforming the codon for glutamine-2153 to a termination codon. Editing results in translation of a truncated apolipoprotein B isoform (apoB-48) with distinct functions in lipid transport. The catalytic component (APOBEC-1) contains zinc at the active site [3].

History
Reactions
Cytosine(6666) in apolipoprotein B mRNA + H(2)O = uracil(6666) in apolipoprotein B mRNA + NH(3).
