Adding two of these chemical groups to morphine results in heroin, and some people are unable to quickly add this chemical group to isoniazid, making normal doses of that drug fatal. The NatB complex is responsible for adding this chemical group to several proteins' N-terminal ends. Sodium butyrate 
Adding two of these chemical groups to morphine results in heroin, and some people are unable to quickly add this chemical group to isoniazid, making normal doses of that drug fatal. The NatB complex is responsible for adding this chemical group to several proteins' N-terminal ends. Sodium butyrate inhibits the removal of this chemical group, and adding it to tubulin is one mechanism of increasing cell motility. It is typically added to lysine residues of histones in order to facilitate transcription by HATs, and it is removed from those proteins by HDACs. It can be added to aromatic systems via the Friedel-Crafts acylation using a two-carbon acyl chloride. Adding it to salicylic acid creates aspirin. For 10 points, name this group with formula COCH3, a methyl single-bonded to a carbonyl.
