Of the five classes of HAT enzymes, the catalytic mechanism for HAT1 and Rtt109 remains unclear. A structural overlay of HAT1 and Gcn5, a more well-known and understood HAT enzyme, found a conserved glutamate residue in the active site of both molecules. It was found that mutation at that active site glutamate residue greatly alters the catalytic ability of HAT1 and has been proven to be structurally important. <ref> DOI:10.1101/gad.240531.114 </ref> Using this information and structurl information regarding the proximity of potentially catalytic residues, the most plausible mechanism for histone acetylation involves the following relevant residues and cofactors <scene name='81/811713/Mechanism_glu_lys_coa/1'>Glu255, Lys14, and AcetylCoA</scene>.
