... Another function of AclB was found to be stabilization of the enzyme, as AclB prevented the degradation of AclA that was otherwise observed in the absence of AclB. After the phosphorylation, ... mechanism of mammalian ACL [23], the final step of the reaction can be assumed to be the nucleophilic attack of CoA to the phosphorylated carbonyl carbon of citryl phosp...
